If you're looking for quality work and a good experience, look no further. I originally took my car to a different shop and had an awful experience. I went in at 8am, waited for about an hour. Wasn't acknowledged. I googled custom muffler shops nearby and found Full Throttle. I spoke to the owner and told him exactly what I needed which was cut my stock muffler after the stock cat, weld a 4" single inlet pipe to the aftermarket muffler, then weld 2 two 4" pipes to make it a dual outlet that leads to quad muffler tips. He understood exactly what I needed done and told me that he could start on my car immediately. While waiting, I met a couple of his returning customers. They were wholesome and made the wait feel short. I did have an aftermarket diffuser that was not a perfect fit which in turn resulted to it coming off while I was driving however I gave the owner a call and he insisted I come back so he can put it back on. He showed me how the brackets didn't align with the stock ones. It's common bc it's not an OEM part HOWEVER he made it work by drilling some screws in. He wanted to make sure I was satisfied before I left. I was more than satisfied. I'm huge on customer service. I knew that everything worked out the way it was supposed to even tho I lost an hour of my time in the very beginning going to a different shop. I will be a returning customer for sure. I had an awesome experience and I was left with exactly what I wanted. read more

Easy going, straight forward and amazing work. They got my car ready for me in timely matter and I love the quality in work.

Writing this review due to exceptional service from Thomas at Full Throttle Muffler. I came to this location even though the phone lines were down due to bad weather yesterday, because of the great reviews I saw online about this shop. It was about 35 minutes til close & I was unsure if they would be able to take me in, but decided to give it a shot. Upon entering Thomas was very welcoming, and asked what the job was on my 24' Crosstrek Sport. I was taking off the stock muffler and installing an aftermarket upgraded muffler. Thomas immediately brought me into the shop to start the install and was such a pleasure to talk to. The whole job took maybe ten minutes at most and came out absolutely incredible. I was so surprised how quick and professional he was. The price was such a great deal as well. If your in the IE & Riverside area do not hesitate to bring your car here for work. I will definitely be back with more work in the future. Thanks for the great experience Thomas I'm in love with the car all over again! read more

horrible customer service called over the phone for a muffler and a resonator got there. He told me I needed a wide pipe. This guy was gonna give me a truck tip on a car when I told him no change the muffler he put the muffler with no resonator and charge me another hundred dollars. Do not come here! Older guy told me to go to mcdonalds if i didn't like it horrible! read more

I took in my 1970 c10 to have my exhaust replaced and I could not be happier with the results. Full Throttle Muffler had a large selection of mufflers and the installer made sure all the bends and welds were spot on. Thank you guys I'm very happy with the results. read more

Swung in there today , to have a bolt aftermarket exhaust installed on my F350 super duty , very knowledgeable and there customer service was amazing. Definitely coming back read more

I took my car into Martin's shop to have a muffler put on when I arrived to pick up the car the front facia of my car had been ripped from all brackets supporting it, and still have not found the brackets, the front end was being held on by zip-ties. To top it off the exhaust was not even welded on straight. In his defense, yes he put on a muffler bracket because mine was torn. So what 100 bucks over 2400? I asked the owner Martin to make this right and his response was "Sh*t happens, next time don't come here" I went through my insurance to open a claim, and my insurance company was not able to get any help or support from his business, or insurance (if any). I have asked Martin to cover my deductible for the $2400 in repairs, he again said "I'm not coming out of my pocket for this, it happens" I will be taking this matter to small claims for restitution and the BAR. This person/business needs to be brought to light as I see the original business under his name has been canceled once and the new license under someone else's name (ref. License 260256) via BAR (Bureau of Automotive Repair) I will keep this review updated, with outcomes. I will not stop pursuing this as I told Martin people should not be treated this way $70,000 or $2000 car, have respect for other peoples property. Be sure to read the other reviews that are hidden at the bottom, my mistake for not seeing them. read more

My second time coming here. Came for a muffler delete on my challenger. I love Martin, he is friendly, and they do quality work. Always fair with the price, and I will always come back read more

Worst place I could've ever taken my car too. They had the worst customer service and didn't fix my issue, after I had gone there I went to go get my smoke check and didn't pass it. Had to go back and they said they had already fixed my issue and didn't bother to try and help out what they did wrong. read more

You guys do not understand when i say DONT COME HERE. Shop owner Martin assaulted me and my camera man during a vlog we were doing of us getting an exhaust on my 240sx. After his worker finished our exhaust we reved the car to see how the finished product ended and upon releasing the clutch my car fish tailed a bit. Nothing crazy no burn out or anything of that sort. The shop guys next door VIP kustomz, along with the shop worker said man your car sounds great, as we were vlogging owner comes out and starts screaming at us and physically hits my camera guys camera out of his hand with a hammer, also hitting his right hand and slicing his arm ( which by the way at this point we're outside his shop on private property) he begins to scream that the dancing studio next door would sue him if we rev our engines. Us in shock we're like dude chill out, at this point we can sue you and take you to jail for assault and battery. We end up having to call the cops to file a report on him and he tells the cops he did assault us and that he's willing to pay for our stuff. After the cops leave he refuses to pay because he says the land lord of the property is going to charge him for the tire mark. We tell him we're willing to take car of the tire mark we left (even tho the whole street is rattled with tire marks). To just give us the land lords information. He refuses to do that too. He tells us to come back the next day and he'll pay us for damages and give us the landlords information. Before we left that night because we didn't want to deal with him yelling any more and we already have the police report we stopped at dancing images and told them the situation and if they had a problem with what we did. The owner of dancing images said she didn't mind anything we did. They can't even hear what happens outside because the music they play is way louder then any outside noises. We return to the shop the next day and it never opened up. So at this point we're going to return again tomorrow and try to figure anything out before we press charges on him for assault. DO NOT COME TO THIS SHOP. Also want to say the worker he has is a cool guy and he apologized for how Martin acted but he said this isn't the first time he does this stuff. read more

Full Throttle Muffler - Shop owner Martin (bald guy) trying to ask shop next door to not say anything to cops we called after he assaulted my camera man - Auto Repair Near Me - Moreno Valley, California

They do horrible work, rude owner, don't know how to weld and too lazy to take down the muffler and weld all the way around, instead he uses jb weld to get to the spots he can't reach and after a while the jb weld would fall off and the muffler would leak, not only that but his prices are outrageous... I ended up fixing the welding my self and I don't weld every day like you would think he does.... Don't go there!! read more

2nd car I've taken here and it was a good experience. My car runs likes it's Jew again! Thank you Martin and your guy in the shop!

I wouldn't recommend this shop just because the guys doing to the muffler half ass his work.

Go somewhere else!!!! read more

I have been here a couple of times to switch out my original exhaust with an aftermarket, and they always do a great job. If you are looking for a good price and great service definitely check them out. Thanks Juan! read more

Full Throttle was recommended to have my catalytic converter fixed and I must admit I was still apprehensive. Well, I didn't have to be, Juan who does the work showed me what needed to be done and had it done in an hour time. He spoke with knowledge and confidence and very respectful recognizing that I was feeling unsure of my problem, he showed me. The price was right and the work was done on time as specified. I HIGHLY RECOMMEND THEM when you hear that funny noise, I'll go back when and if I have the same problem with my other vehicles . You can trust them to be honest and professional . read more

It was my last stop to complete my journey on fixing my SUV, and it couldn't have ended in a better place than here. Mark is a good man, he explained and help me get 2 cat converters that I need to pass emissions. It made sense what he said, and I left there a happy customer. Very affordable and a pleasant experience. Thank you Mark, God Bless you my friend. read more

Worst Place I have ever went to for auto work done. This place totally robbed me and threaten to keep my vehicle after I had already paid the quoted price. Upon paying the quoted price I was then told that it was going to be $90 more. I even help the mechanics work on the vehicle! The owner is a real scammer and took advantage of me. I refused to pay the price that he was trying to charge me and he started locking up my vehicle in the shop. The owner is very argumentative and very unprofessional. Only out to cheat you out of money. Even the Mechanics that worked there could not believe it either . Never in my life will I return to this place!!!! read more

I had noises coming from my exhaust and they fixed it in about 15 minutes when Advanced Muffler told me it'd be 2 hours & they didn't know what it was. I had 2 leaks and a broken bracket. Great customer service. read more

I had a catalytic convertor stolen from my vehicle. Full Throttle Muffler guided me through the process of filing a claim for the stolen part and once that was accomplished, they installed the new part. However, upon a recent smog inspection, it was discovered that the part was illegal; the catalytic convertor Full Throttle installed did not meet the requirements for California Emissions. They new this since their specialty is mufflers! They blatantly ripped me off and it will cost me hundreds to fix their illegal actions. I hope they are inspected! read more
