1300 estimate x 2 (verbal from one, written from another) to install headers and weld cats on w/minor custom work. Gave detailed written instructions in addition to instructions for header instal with $1300+ worth of materials (headers, exhaust studs/nuts. Discussion w/owner/manager? about the instructions. Job done by "kid" in shop in 1 day, Charged $2350 w/"discount". replaced my Toyota cats w/crap cats against what I told them to do, didnt weld on cats, created impossibly complex flange system that constantly loosens and is incredibly difficult to get to, removed a cat back flange for no apparent reason, didn't use the tip I gave them but put a new one on that routed straight back against what I told them to do (route to side behind tire). Took because I needed car and lived too far away. Had to bring back for rattling tail pipe for which they added a "hard mount" that shed its bolt. Brought back for multiple bad welds. Left over night and was oversprayed by paint or primer that took me 4 hours to remove w/clay bar. Tried to make system work because I live too far away to bring back again but now again leaking and loose and rusting well beyond what should be reasonable for a 3 year old install that is kept inside and meticulously cared for. Can't tighten bolts for cats. $3500 invested in what was supposed to be a solid custom job and I will have to bring to someone else to unscrew. Didnt realize they took Toyota cats and replaced with what look like generic Chinese crap until recently. Smell bad and throwing codes. I would not trust them to fix the problem so chose to share problems. Can't help feeling like I got screwed. read more

Friendly quick service with reasonable price. What more do I need to say? They want 85 characters.

Scott and his team are great. I saw the great reviews and decided it was worth it to drive an hour away to have them install my cat back exhaust on my 2024 Nissan Frontier. They did not disappoint. I showed up and they were really nice and let me sit in the garage to watch them work on the truck which was cool. I felt like a part of the team! The pricing was affordable and they do such high quality work. Fast forward to 4 months later after I had my 2.5" lift installed, the exhaust needed to be adjusted as it was making contact with my rear shackles, creating a rattle noise. I showed up same day and Scott made the adjustment free of charge. These guys are professional and love what they do. They also are honest and have great customer service. I will be coming back in the future. Highly recommend Hi-Flo Custom Exhaust for all your exhaust related needs. read more

Went in for a exhaust tip weld for my '22 Honda civic. Did an excellent job with the weld and was inexpensive

These guys are TOP SHELF...I went in there to get an aftermarket exhaust welded together with dropoff. They were like no need to leave, we've got it...while I was seeing my car pulled into a bay! It was that quick, and four dudes stopped what they were doing to check it out. They were like we'll be done in a sec...I saw some old school cars being worked on and asked could I see them. A Tech showed me and they came over to say they were done and to take my time. Owner only charged me $60, I'm like wow! U sure? He's like for sure...just the best value and service ever! Highly recommend and apparently most fixes are same-day. read more

Trustworthy, fast and affordable. I would definitely recommend them! They stayed true to their word on estimate and time it would take to fix my daughter's muffler. read more

These folks did a dual exhaust install on my '66 Mustang coupe as a sub to my auto restoration/repair shop (Pro Speed Auto). PS recommended them after determining that Hi-Flo could fabricate and install a stainless steel dual exhaust system for less than it would cost to buy and piece together a stock aluminum reproduction system. Picked the car up today and checked the exhausts on a lift. They are exactly what I wanted. Thought I would do a shout out to Hi Flo. Thanks, gents. Charlie Buhl read more

I would give them a 10/10 if that were an option! They did an incredible job straight-piping my TRD Camry. The staff is wonderful, hardworking, and incredibly helpful.

I restore MGs as a hobby and have used many shops for specialty work. This business is top of the line!!! From Scott at the front desk to the shop foreman to the guy that did my work. This place is the best of the best. I am writing an article for my club newsletter advising anyone needed exhaust work to go to this shop. They did difficult dual exhaust system on my 78 MGB and the design and quality of work was excellent! I wish every business was like this one. Ed Johannemann read more

My 2014 Ford Explorer failed state inspection for leaking exhaust and upon further inspection, it seemed that the weldings on my mufflers were starting to deteriorate. I was originally quoted for $1,200 for repairs. I dropped off my car here and they gave me an estimate within 20 minutes and quoted me for $500. They fixed my car within an hour and a half. I passed my state inspection. They were fast, reasonable, and nice people. They do charge you for a credit card convenience fee but I had a bank nearby from which I was able to withdraw cash and avoid that fee. read more

Overall excellent facility was very clear and easy to deal with each time I called he explain the steps they were going to take to fix my exhaust pipe any and they ended up fixing it with no issues making a very clean job and ended up charging me zero dollars great people will 100% be back to do business with them again could not say it anymore this is the go to place for muffler and exhaust issues read more

I have taken my truck to this shop on several different occasions and have had bad experience each time. The work appears to be professional but that where it ends. Made appointment which stupid me figured that the day work would start. I guess the shop got tired of me nagging because I was told to take it someplace else. My truck was parked there for 5 months and in the shop 3 days. Even the headers I had installed needed to go back 4 times for leaks. Be very careful, also cash business. So no recourse. read more

I definitely recommend this business Scott the owner is really cool down to earth dude helped me though the hole process you can't beat the price for the quality of work the work is really good i give this place 5 stars it was my first time coming there i definitely will be going back great place to get exhaust work an anything else done -William read more

While checking Yelp ratings/reviews for exhaust work, I noticed that a friend of mine gave Hi-Flo 5 stars for custom work on his car. So, I called and Scott [owner] was friendly and direct when I mentioned that my aftermarket performance exhaust has issues fitting/hanging correctly. (Even with a "fitment guarantee"!) He said that I could come right away and get in. I did go right away and had my car in the air within minutes. Scott and his crew are consummate professionals. So knowledgeable and friendly. They listened to me and I felt very appreciated and comfortable. The work was done incredibly fast and 100% to my satisfaction. Price? Wow, very affordable. I even told Scott that I would pay more and he declined that! I gave my car a quick test drive and still had a totally unrelated noise/rattle that the team there helped me troubleshoot. All just out of kindness. I cannot give better praise here. I fully recommend Hi-Flo. I will not do work myself any longer. I will go directly to Hi-Flo. read more

Just go there, you won't be disappointed, read other reviews. Very reasonable and no nonsense. They give you all the options up front.

I brought my 2003 Chevy 1500 in because the person before me took the cats off and had a Dumped exhaust on the passenger tire. It was very clapped out and too loud. Scott and crew are very friendly and did more then expected, put two new o2 sensors and hooked up a muffler piped to the back for the work truck it's very quiet and I can now hear my thoughts. Im now going to take the truck back to the shop next week for them to diagnose and fix a engine issue. Raul seems to know alot about these GM LS motors. read more

I called the same day to ask if they could get my resonator deleted and I was in and out within an hour and a half. Super nice guys, quick but quality work, and a nice shop. read more

After a while I have decided to quiet down my car that wielded dual Roush catback exhausts. It was too loud at low rpm and had too much drone which also gave me headache while driving. I came back here a 2nd time and reinstalled mufflers on my exhausts and it made my driving experience WAY more smoother and comfortable. It didn't take a long time and I got my car out of the shop within hours. Great service as always. read more

I came in over a year ago with an x-pipe, mufflers, and tips for my 2005 CTS V to have a full exhaust welded up and they did a terrible job. The welds are horrible and they did not finish welding all the way around the tubing leaving me with multiple leaks which were very noticeable and the car smelled in the cabin. It seemed like they also were trying to hide the work they did as they had already pulled the car off the lift when I came to pick it up and were trying to rush me out. Now I have to take my exhaust to another shop to finish the welds. read more

First time personally using this shop but was recommended to me from family members. This place is a straight to the point shop. The guys here are great and do solid work and won't BS you about what is needed and offers very fair pricing. I had an appointment at 10am and by 10:10 my car was on the lift and already getting started on and my car was completed by 10:45. The work being completed was an axle back exhaust installation with having a new pipe cut and welded in. I will gladly recommend this place to anyone and i will gladly be returning for my future car needs! Thanks guys! read more

Hi-Flo Custom Exhaust - My truck - Auto Repair Near Me - Manassas, Virginia

I was referred to Hi-Flo a few years ago when one of our vehicles failed an emissions inspection. Hi-Flo examined the vehicle the same day and quickly fixed a minor issue for a reasonable price. The vehicle then passed inspection. I've been a loyal customer of theirs ever since and always had quick service and fair pricing. Today, my wife took our van in because of a persistent rattle near the muffler. By looking under the car, I deduced that the heat shield was loose and rattling against the muffler. That was indeed the problem. The Hi-Flo mechanic said it took him 10 seconds to fix it once the van was on the rack, and he did it for no charge. I highly recommend Hi-Flo to anyone who needs exhaust work done in our part of Northern Virginia. read more

These guys are the best. My second time being to the shop to get some work done. I had some exhaust work done on my car. Through no fault of theirs, I picked put exhaust tips that were a bit long for my car. Brought it back few days later to get them removed to install a different set. I had budgeted about $150 to get those swapped out. To my surprise, once the work was done, Scott the owner just handed me my keys and said see you later. I said you are not charging me, he simply said it pays to be nice. So he basically rewarded my respectful and cordial interaction with him and his staff. I could have gone in there trying to shift responsibility but I owned my mistake and was ready to pay for it and low and behold a kind gesture was awaiting. They have a life long customer here for sure. read more

I brought the car in to get the exhaust and cat welded together. When the vehicle was done, as I was going home, I noticed the exhaust was rattling so I took it back. Scott was super cool about it and finished the job. I know this shop owner really care about the customers and because of this, I will go back and recommend to others. Thanks again. read more

Great service have have great quality exhaust system have extraordinary welders that know what are they doing really recommend the place

This review is LONG overdue. I found Hi-Flo about a year ago on yelp. Scott was a straight shooter and told me exactly what I needed to do without trying to haggle me for additional work or unnecessary repairs. I've brought my truck in a few times since, and every single time they've all been incredible. These guys are amazing! Awesome work, fair pricing, honest and reliable! read more

If you're looking for the worst case scenario, unapologetic condescending no mask wearing "know it all" shop, look no further! Perhaps you're looking to get cussed out or get your cars heat shielding and bumper destroyed while they hacksaw your old muffler off ? Come here ! I had my car worked on (resonator delete and some new tips) and in barely over a year they slowly started sagging at the weld points and dropped down until they scraped the road and fell off. I came to them tips in hand and asked if they had some sort of warranty or if they could help me out by cutting me a deal on welding them back on. After all I was a return customer, and I had spent $50 two different times in two different cars switching the muffler back to stock, so I was assuming this would be a $20/$50 fix. They put my car up on the lift and start hacking away , stopping literally halfway through to confirm that this was going to cost me $150. After trying to explain myself and the whole situation, I told them that I thought this was a warranty / poor craftsmanship issue.. and that Hi-Flo should consumerise the difference. They didn't know what that word meant, to which the owner came out litterally yelling and cursing at me, accusing me of trying to cheat him, his "men" and his business. I tried to de escalate the situation by trying to explain myself and the situation, but was only yelled at and cussed at more for not calling him "Sir", and calling him dude instead. They lowered my car, and revved it out of their shop, telling me to get the f out. They messed up my vehicles heat shielding, and cut into my bumper. Put your exhaust on with chewing gum if you have too.. but do whatever you can to stay away from these genuine jerks. read more

As work on my vehicle goes, I like to wait a few weeks for writing a review to make sure that everything is solid and keeps working as expected. I am happy to say that for the last two weeks, my custom Magna Flo exhaust is exceeding expectations. The welds look great, there are no leaks, no rattle and the sound is superb. I believe in the motto " you get what you pay for" and the price was not cheap, but I am fine with that when it comes to getting quality work and parts done. For a chrome dual catback system with a Magna-Flow exhaust ran 650. Something I'm willing to put down for the quality work I've received. Scott was professional, estimate was quick and fair. read more

These men are legit. I called before coming in, they gave me an estimate after I told them what I wanted, and did the work promptly and efficiently. 10/10 will come again for future projects. read more

I called to see if they would be able to take me and Scott told me to bring my vehicle in. I have a 2007 Malibu and wasn't sure they would have the part. When I got there my vehicle was taken right away. Scott showed me that the resonator needed replacing and he would be able to replace it right away! He said other shops may have wanted to replace all the exhaust from front to back for a lot more money but it wasn't needed. I was thrilled to save some money on the repair. A considerable amount of savings!! He showed me the finished work. The welds looked good and I was out of there in an hour!! Scott you made my day!! A++++ rating Thanks!! read more

This is my go to shop for any maintenance and aftermarket work i need done to my 01' Mustang GT. I found them by calling around to the best rated shops around me, and they offered the best price by far for installing my new suspension. It's hard to find genuine and quality work for very fair and affordable prices. I live in Stafford, but i do not mind driving 45 minutes every now and then for a great deal. I have visited the shop 4 times now, and the owner Scott always offers the best customer service. They go out if their way for me and i greatly appreciate that. read more
