I have been coming to this place for a couple of years. He has smogged all of my cars. I have referred him to friends and family and they use them . However , my recent visit(12/20/25) has changed my view on them . Their smog tech's knowledge is lacking . My car's catalytic converter was stolen last year . We purchased all parts from the dealer and had them installed by a local reputable muffler location . ( catalytic converter , oem flange , oxygen sensor , gaskets , upper and lower shields misc hardware). We added a miller cat shield to protect it.. I brought him my car for a smog. He told me everything lookred good, except the visual? I said why? He told me that the catalytic converter was the incorrect one. I told him it was the OEM part from the Manfacture. He disagreeed. I told him i had the reciept from the dealer where the parts were purchased. He told me he wasn't going to charge me but to bring it back the car with the documentation. No failed docuemntation was handed to me . I printed all records from the online dealer purchase and returend. I was greated by a different smog tech. I told him that the previous tech told me to come back to smog the car. He reviewed the car and told me the car had failed. I was confused as the first tech didn't not say anyting about failing the car. I told the new tech that i had brought it this location. He asked for the documentation. I told him the gentlemen that reviewed the car told me he was not going charge and not docuemenation was issued. I told him that if the tech failed it you smog system should have a record. He goes and looks up the car to see who pefromed the test and found it was the smog station they run. He printed out the failed report The new techc said, come back when he is here as i don't why he failed it. I asked him when the tech will be back? He stated in 2 weeks? SMH.... 2 weeks? i can't wait that long. I reverted back to the smog /repair station i went prior to finding this shop(its closer to my home). Guess what it passed the visual. Never again will i come back. It is unfortunate. 2 stars, the lack of knowledge is unacceptable. The inablity to identify an OEM Catalytic converter from the Car's manufacture is a problem. read more

Smog - OEM catalytic with miller shield. - Smog Check Stations Near Me - Orange, California

I went here on my lunch break, I had one car in front of me. I was in and out quick in 15 min and got lunch and went back home to werk:) great place, back of shell! 65$-70$ range Good customer service and clean station and good price value. read more

Been using this smog check place for years and they usually have a coupon online if you look for it, but also appreciate their flexibility with test and retest as well as being clear about cost of all the charges. Likely not the cheapest smog place around, but convenient quick in a good location and easy hours. If you can't find a coupon online they might accommodate you in person with a small discount, especially if they see that you brought your car there before. read more

Nice guy with a tiny shop hidden behind a Shell gas station. I needed to get my wife's car smogged and I took it elsewhere and they failed us because the car's computer said it was not ready (fair enough, not the shop's fault), but they would not retest free even through they advertised it. Came here and he checked it, said it was not ready (for free) and told me to drive it a while and bring it back, When I came back, he checked it again then did the smog test. Another customer was there and they had the same issue I had at the other shop, but he told the guy to drive and and bring it back for a retest for free. That's how it should be. read more

Says they are up until 6. Showed up at 5:30. No bueno. All locked up. Wasted my time.

I found them online and was very impressed. I arrived 5 minutes before closing, he had 2 cars before my pick up truck but was eager to stay late to serve me. A very clean smog check location - the best place I have ever been. I will return. Well worth the extra money because of the quick service and cleanliness. read more

Arrived and was greeted immediately. The service was completed in a timely manner - 5 stars. Would recommend.

My dad told me to come in for a smog check and I had no clue what I was doing. Thought I was gonna get over charged like usual but the gentlemen was very kind and I got charged fairly. read more

Super easy and service was fast. All together I spend there 10 min. Great coupon was available on yelp.

The guy who owns this place is very nice and he gets straight to Business. Don't waste no time and I was in and out in under 10 minutes and I appreciate his patience of him answering any questions I had so I highly highly recommend you guys to go here to get your smog check. read more

They completed my smog check in a quick and efficient manner

The guy was fast and efficient but when I asked about the yelp $15 off coupon he added in a "smog cert" fee which was $8. Value of the coupon was $7. Total price was $45. Not a great value, but decent convenience. read more

This morning I needed a smog check for my truck. After a horrible experience and being told my truck could not be smog'd because a sticker was missing on my super charger I went to smog pros. Romeo welcomed me and got me right in. He took the information I had and did the smog in 20 minutes. The best customer service I have had in years and I recommend anyone looking for excellent service to bring your vehicle to Romeo. Thank you Romeo for your professional service. read more

Part of the shell station located in the back. Check-in on yelp immediately and show them the $15 off coupon before they hand you the paperwork. Romeo was friendly and quick to work. You pay inside the shell station. read more

Came to the business with a specialty vehicle with modified exhaust. It passed all smog equipment test parameters per california state law, even while missing the secondary catalytic converters. Instead of allowing this vehicle to be cleared - even tho emissions passed - the car was flagged by the employee of the business in a california database as "tampered". I now must replace my exhaust system to clear the car's lien by the state. Sure, we can make a point that CA state law requires four cats and not two. However, the car was a pass in all emissions fields. You tell me. As a note, the shop has smogged this vehicle before and yet the last time (with the same specialty mods and same person) the car was not revved multiple times or visually checked. It felt immediately discriminatory as a result, like a fast car should be checked extra over the minivan that came prior to it. Do not recommend you bring your specialty vehicles to this shop. Stock vehicles sure. Not specialty - you'll be out a lot of money. Thanks a lot bro! read more

Service was fast and staff were nice we were in and out. Will definitely be back again next time

Make sure you present the coupon before douchebag does his 2 minutes of work for $58 goddamn dollars otherwise he'll give you shit about it and make it seem like he's doing you a favor by giving $10 off instead of the $15 off. No where does it say you show it before work gets started. Usually with a coupon you present it when it's paid. Fuck off my guy. read more

I have an old car, and I don't drive it often, so gunk collects in the tailpipes. I keep it in perfect condition but it often fails the test. They don't try to rip me off for fake repairs. They are always friendly and understanding. They do the test quickly and charge a fair price. read more

I used these fellas and the Napa car care next door Good honest folks . Friendly and informative fair and honest read more

I initially called for a quote to get my car smogged. Boy am I glad I did, I ended up saving myself $50 bucks (which isn't bad) for a smog I didn't even need. The guy who answered the phone had exceptional customer service and asked questions about my car and why I needed the smog. I am privately selling my 2017 Toyota Tacoma and the DMV was telling me I needed a smog certificate as part of the paper work. Thanks to Smog Pro I found out the new law states that any cars younger than 4 years old DO NOT NEED a smog. He knew his law so well that he even said I could come down to the shop and he will give me paper work confirming this law to provide to the DMV. I brought this information back to the DMV and what do you know... he was right and I was able to finalize the paper work for the sell. Thanks soo much for your outstanding customer service and knowledge of the auto laws. When I do need a smog I will definitely be coming here for it. read more

This was so easy (went during my lunch hour) drove right in and there was a gentlemen by the name of Romeo (inspector) super nice and polite. He was very informative told me it would take about 20 mins and please sit and wait. Place is clean and they get you in and out quickly. I would definitely recommend this place to anyone that needs a smog check. Also included a free car wash! read more

Dude that runs the smog check pissed me off. He failed me for a legal aftermarket filter that had passed at this same location two years ago. What really made me mad was the guy could have told me as soon as he popped the hood he was going to fail me before he wasted my time hooking up to the obd2 scanner and running my truck on the dyno, which forced me to have to pay. I would have come back if he told me I needed to fix the problem... I would have respected him for that, but now I'll take my two vehicles, and my girlfriend's vehicle elsewhere. read more

I walked into Smog Pros for a smog check on a Wednesday afternoon around 4:30 and was delighted to find that they were not busy at all. The manager asked me to my pull around back and they immediately got to work. I sat in their garage for around 20 minutes. The price is a bit more than you might find elsewhere. I know many places advertise 29.99. I don't know how they compare to Smog Pros; I would imagine there might be quite a wait. I had a coupon for $10 off which brought my total down to 48.00 In my opinion, a sign of great businesship, is in the small things. My license plate has been hanging off the front of my bumper for the last month or so; something I keep meaning to fix, but never do, because it requires the right screw and most precious, my time. One of the mechanics noticed my plate and while the car was being smogged, set to fixing it. He smiled at me when he was done. "All fixed." I was floored, quite frankly. It was not his responsibility to fix this for me. Time is money. However, it was this bit of kindness that sold me as a customer. In the future I will return here for smog checks and recommend Smog Pros to friends and family in the area. Kindness and honesty will get you where low prices and convenience can't. read more

Day 1: I brought in my 1989 Toyota mr2 for smog but there was no nitrogen left, which is required for older cars. They told me they will have more nitrogen by tomorrow morning. I said no problem, I'll be back tomorrow. Day 2: Came back the following day in the afternoon to smog my car but they still didn't have any nitrogen. Day 3: I called ahead to make sure they had nitrogen. They said they did and they could smog my car now. When I got there they couldn't figure out how to calibrate their smog machine and wasn't able to smog my car for the 3rd time. Left and found a small smog shop around the corner that was actually about $20 cheaper. They were done with my car in about 20 minutes and paid $50 as opposed to $70. read more

I found this spot last minute on Yelp. Super stoked when I realized they were open on Sunday. The technician was extremely helpful and provided me with pricing prior to commiting to the Smog Check. Once he looked over my vehicle he offered me the coupon discount and completed the process within 20 minutes! The icing on the cake was he drove my vehicle to the front while I paid! I definitely would recommend. read more

This place was fantastic. I had a coupon for a place down the street, but their machine was broken. So I drove up Tustin until I spotted the next smog check sign and this is where I ended up. Romeo was polite and got my truck in and out quickly. And the price was better than it would have been at the first place I went, even without a coupon or deal. The whole experience was as pleasant as possible, for a smog check. I will come back here the next time the DMV says I have to. read more

These guys are awesome! I showed up on my lunch break, was met by friendly staff who took my truck immediately. In and out in under 30 mins! This is my 5th time here over the years. I totally recommend this place. It's hot = wish they had AC, but hey... It's a garage! read more

Smog - These guys are good. I showed up on my lunch break, walked right in and had a friendly employee do it right away. - Smog Check Stations Near Me - Orange, California

Wouldn't recommend this place! I didn't know that if your check engine light is on you automatically fail smog test which is what happened but that's my fault. But you would think the gentleman working there would tell you that since he's in the customer service industry but instead he proceeded to take my money and then fail my car for smog. Took it to my mechanic to fix the issues with the check engine light. Brought it back to get smog checked and he failed it because i hadn't driven it 200 miles after the repair. Don't waste your time, there are cheaper smog stations down the street. read more

They may close earlier on Sundays, depending on how busy it is, so make sure you call ahead of time. We were in and out of there within 15 minutes. Not much of a wait on Sunday and it was quick and easy. Go around back of the gas station to the Smog Check center, they run the smog diagnostic for 10 minutes, once completed you walk around to the attendant in the Food Mart to pay. Quick, friendly, easy. Not much more to say than that! read more

Excellent service the guy very honest about the issue with my car I was able to go buy the hose that my car needed it he replace it and smog check passed second time same day . read more

Vic at my local Valero said he could not smog my daughter's 2000 mustang because they were not a "star" station. They recommended this place on the corner of Tustin and Collins in Orange. I highly recommend this place. Romeo, a very kind gentleman, performed the inspection. Fast, cheap and a decent place to sit inside the garage so you can watch them work on your car. I was very pleased and intend to return with my other 3 cars. Thanks Romeo! read more

A week ago I was lost and needed gas and stopped at a gas station with a car wash, I did it just because it was handy but today I came back because Richard is so courteous and helpful were the car washes Department. He is the sweetest gentlest person with a great personality and love for his job. You must try this gas station / car wash car wash is great! free vacuum, clean store, it's the best service I've had in a long time my husband and I will continue to use the service even though. it's a 10 mile drive for usbut week worthworthit!. Again when you need a car wash this is the easiest and best kept secret in Orange. read more

I called for price and availability on Monday morning after dropping my kid in daycare. Romeo told me $58 out of door and available immediately. I arrived in two minutes but found there were two cars ahead of me. When I confronted Romeo he said the two cars "just pulled out". In two minutes all of sudden two cars pulled out? You must be kidding!!!! I decided to call another station. I got price match and immediate availability. In a word, there are NOT HONEST. Don't do business with them!! read more

The absolute worst most unprofessional experience I have ever in countered. Young Kid, who is clueless about autos and smog issues made up excesses why he did not want to smog my LEGAL CARB APPROVED vehicle. And insinuated that my vehicle was stolen. I am insulted by his accusations and would not recommend this shop. read more

Romeo was very nice and professional. Very fast and good customer service! I only waited like 20 minutes for the smog check to be done and I was out! I will come back for my next smog check. read more

Great service! My car was in on a Saturday morning and I expected to wait on a weekend. The man who serviced my car apologized for the wait but it was not that long (30 minutes). Only two people were ahead of me at 8:40 a.m. It was not a bad wait time at all. After my car passed the smog check, the service man sent in the certificate to the DMV. The total cost was $58.20. I told the man (who I should have gotten his name...so sorry) that I found him on Yelp and I will refer others to him. read more

Smog check places are mostly customer service. It's a pass or fail service, that's it. People really want kind quick service and someone nice to break the bad news to them without shame on the customer. So this guy runs a dual station so he gets cars done quick. Prices are clearly marked and he has a place for you to sit and wait for your car. He recognizes you as a customer right when you pull up and shows you where to go and what to do. Earning a five star for this place means they must be open in Sundays! Yeah!!!! read more

I wanted to get my smog check done quickly, and the shop I usually go to was closed. When I arrived at Smog Pros, there was no wait, and I finished smog check and was out in less than 15 minutes. You can find better deals elsewhere, but I just wanted something that was quick and hassle free, this was perfect. Smog check for a 2006 Civic costs about ~$50 + $8.25 for the certificate. Thanks Jose. read more

Took my 1988 Land Cruiser here today and Romeo was very knowledgeable, fast and efficient. Found a coupon online also.
