My 240,000 miles car needed to have the manifold gasket replaced + heat shield fixed (fall on the exaust pipe due to corrosion). I brought my car in few places to get quotes and Lous was 2 to 3 time cheaper than all the other place. I dropped my car at 8am, and was ready at 1pm. I highly recommend them.

Absolutely awesome place; Cody and his team did a great job, and are super friendly; I went here through a warranty claim from CarMax - Id never heard of them before; Ill never go anywhere else again. Great service. Great team!!!!

I’ve never written a google review before... and I needed to go out of my way to put this out there. These guys are amazing. They do high quality work at a fraction of the price of anyone else in the area. They are friendly, explain the situation and give you an honest quote- I wish I had another car I needed to fix because I would bring it here. Don’t go to the dealer or anywhere else!

One of the best exhaust shops in Massachusetts. Cody and his team are extremely knowledgeable and have true passion and skill for their craft for just a fraction of what other shops charge. I drove all the way from Middleton to have a secondary cat delete, resonator delete, and have magnaflow mufflers welded to my Mercedes-Benz E550 and it sounds just the way I wanted it to. This is the only place to get your exhaust work done, I can’t recommend it enough!

Thought I needed cats, but these guys went above & beyond when they stuck a camera inside to see if a replacement was necessary.And it wasn’t. They aren’t even charging me for their time & effort. I’m not one bit surprised these honest guys have a 5 star rating. They have a new customer for life, and I’ll recommend them to anyone who needs exhaust work. If you guys at Lou’s see this message in time, feel free to stick a Lou’s Custom Exhaust sticker anywhere on the rear door of the white Chevy Express box truck

By far the best Lous out there. Brought my Audi RS5 here for some custom exhaust work and just recently my Honda Type R.. These guys do amazing work and id never consider going anywhere else. A+ all around!

I engaged Lou’s Custom Exhaust to replace the aged and restrictive factory exhaust system in my 2009 Infinity G37x Coupe, with a custom high flow Cat performance system Jan 2020 The result is truly impressive. The exhaust note is superb at driving speeds and sounds absolutely ferocious from 4800-8500 RPM.I was so impressed with Cody’s attention to detail, the manager of Lou’s in Marlborough, I decided to engaged Lou’s to begin the first phase of a full restoration of my G, with the installation of an Infinity factory performance brake kit, a complete factory performance suspension system, Hotchkis performance sway bar kit, a K&N fresh air Intake system and because my G has 115K I had them attend to about 20 other small engine and chassis maintenance issues.Cody and his crew are amazingly dedicated team that can’t be beat on craftsmanship or price....I highly recommend them for all your performance and daily driving machines.

Great work, great price, quick, only do whats needed. Super nice employees, friendly, hated working and respectful. Like cracked from fatigue, they fixed it and added a flex joint so it wont happen again! I wouldnt go anywhere else and all the Lous locations are just as good.

I had never heard of Lous until I posted a short video of my exhaust leak online. More than one person (including a mechanic) had suggested Lous, saying these guys were great and would save me money. With a 12 year old truck, I would rather repair what could be repaired and not be told I needed a complete new exhaust system. After seeing great reviews, I had called in and spoke with Cody, who was very friendly and professional. I got a quick appointment, the repair was assessed, approved and completed quickly. The price was very reasonable. I would have expected to pay way more somewhere else. Its no wonder these guys have great reviews.. They know their business very well! Thanks guys.

10/10 would recommend. 👍Cody is super nice and easy to work with. He did headers and cats on my SS Camaro. Quoted me a price to install and stuck to the price. He also found 2 exhaust leaks and welded them for me. Scheduling was easy and on time. I drove from Haverhill to Marlboro to have him work on it. I will definitely be back to have any other car done done with Cody. ☺️

Called on a Friday afternoon to see if I could get a muffler delete on my car, was able to to get the car dropped off and back the same day. Sounds great. Will definitely go back in the future.

Made an appointment to have the car looked at. When I got there, they pulled the car right in, no waiting. Then showed me the problem under the car. Figuring I would have to come back another time to have the work down, Cody said he could work it in while I was there. They did a great job! Fixed it on the spot in the time he said. A very professional and courteous shop. The shop was very clean too, which shows they take pride in their work. Highly recommend this shop.

Forgot to post last year, I had the full exhaust replaced on my Suzuki Samurai. It has a VW Diesel engine in it, so nothing factory would work at all.Brought it to Lous of Marlboro and they took a few minutes to look it over, gave me a great price on a stainless 2.5 system from the turbo all the way back, and he put on a nice black tip that really fits the look of the rig.Thank you for great service!Ill be bringing my TT in this week... previous owner had the exhaust repaired somewhere else and it still leaks, I have no doubt the guys at Lous will get me fixed right up.

Nice place for a custom exhaust. Prices are fair Work appears excellent. Estimates are free

Quick, cheap, and quality! I called up for a rough estimate for a new flex pipe, which he gave over the phone, off the top of his head. Total call took 20 seconds. Dropped the car off and got it back in less than 2 hours. Total cost was exactly what he quoted over the phone.

Best shop ive ever been to. 6 beautiful welds in a few hours at a good price. Need i say more?

I had the exhaust from the cat. back totally off of my daughters car. When I went to put on the parts I had ordered nothing fit. I called Lou’s and Cody told me to bring it over and they would take care of it. They got all of my parts to fit and did it quickly and at a very reasonable price. Thank you gentlemen. I would highly recommend them.

Great service great employees awesome price and quickly done!!!! Thank you

Brought 2 of my cars here. Decent prices and good work

Excellent service and good prices. Had to have flex pipe installed and a catalytic converter (that I brought with me) welded in. It took about 30 mins and it was done! Definitely going back for any future exhaust work.

Brought my car to get my exhaust installed, was done in couple hours and sounds amazing!!

Professional, well organized, fast service with competitive prices

Brought my 2014 Mitsubishi Mirage in for a catback ( Dont laugh). I called ahead and was able to get right in and the guys got down to work. They helped me select the right pipe size as well as an appropriate muffler. I was happy to find out that they could supply stainless as well to survive these New England winters. My little 3 cylinder left there sounding better than I thought possible. Nice deep refined rumble, not angry bees in a coffee can noise. Money well spent.Update: five years later, I still have the Mirage, and the sound of the exhaust still makes me grin. Many have been surprised to find out that it’s a three banger that sounds that good. Very pleased.

Heard a lot of good things about this place then had an issue with my jeep. I pulled in without appointment. I left it, they called within an hour with estimate and my rig was done mid afternoon. Exhaust looked and sounded Great! Couldnt be happier.

Got in at the last minute and they really help me out thanks again!

Cody has now deleted my muffler and built a custom Y pipe for my bmw e90. Sounds beautiful great work and super reasonable price for full stainless steel piping and super quick service. Wouldent trust my Beamer with anyone else. period.

I was absolutely impressed by the professionalism and outstanding customer service. My car was taken in at a very short notice, problem immediately diagnosed and all repair work completed in half an hour: cutting out the rusted exhaust joint and welding a new one.

I decided that these guys deserved five stars, they try that hard. They do all auto repair now, so dont be shy about asking. Im giving a shout out to Luther, who pleasantly answered all my questions, even explaining how they found out that the fuel pump was gone. I will be back, and I will recommend Lous.

I happily recommend the Marlborough location of Lous. I explained what I was looking for out of my exhaust, and they delivered exactly what I was looking for. The price was right, and the service was fast. I was pleased to see a clean, well stocked shop when I walked in as well. Thanks guys.

Prompt,professional,courteous service at a reasonable price for my relatively minor exhaust issue.I highly recommend this shop and I will return as a customer

Highly impressed with the shop, specifically Luther and Cody. Showed up with an aftermarket axle back exhaust without all the proper hardware and they had it welded to my midpipe in no time. They made sure the fit- up was to my liking along with the position of the exhaust tips and were totally approachable about me making sure we checked that some stock hardware wasnt effected/remained the same after the install. Car looks and sounds awesome. Will be bringing it back in shortly for a custom x-pipe that they gave me a great quote on and showed me previous examples of their work which looked top notch.Thanks again, guys!AJ

These guys are amazing. Saved me so much time and money. Awesome dudes and awesome service, will absolutely be coming back here from now on as they do full repair as well. 5/5 for sure.

Awesome place to get service done. Talked with them on the phone and described my situation for replacing my current mufflers with new custom ones I bought on the internet. The manager gave me a rough quote of the price and the end price turned out to be pretty much the same! The guys were extremely pleasant to talk to and definitely made the atmosphere a comfortable one. They let me watch them work when I wanted to and I could see their attention to detail and pride in their work. They didnt cut any corners and let me know what they were doing/going to do as a courtesy which made me feel more comfortable. The job these guys did in my opinion was very professional, timely, and simply done right. I will definitely be going back to them when I save up for an X-pipe system to be put in. I hope the Worcester site is just as knowledgeable and easily approachable as these two gentlemen were.

Weve used Lous Custom Exhaust for a few years now and they have impressed us each time weve needed exhaust repair work done. Today I brought my wifes car in since the exhaust was suddenly making a terrible noise and they contacted me within 30 mins to let me know what needed to be done and had it repaired and running quietly by late morning. Pricing is reasonable and the staff is friendly. Highly recommended.

If you need exhaust or just want duals look no further. Very professional and quality work. I love the look and sound of the dual exhaust they just put on my truck. Awesome Job, Thank you

Quick work. Very fair about what work should be done vs what could wait. Price was right and quick turn on getting it done while I waited.

I asked for a cat converter quote and said $650 including labor...went to another place got it done half the price including labor. cant blame them its there shop but if price is right for anything else go for it. might pay them another visit. the guys in waltham are very friendly and they dont force you to buy anything though.

Had a section of rusted out exhaust pipe that I kept patching, when it finally gave out, I went to Lous, explained the issue, was given a ballpark quote of a little over $100. Brought the car back a month later, dropped it off at 3pm on a tuesday, they called me to let me know if a few other small issues and how much they would be by 11am the next day, I went with the original repair only which was more extensive than I thought, and the bill came out to $150 even, which is what I expected for the original lesser repair. These guys are honest, do great work, good welds, good knowledge, great price and will accommodate after hours pick ups and drop offs. Could not reccommend them more and I will be back when the next part rusts out.

Thanks again guys for the new exhaust and muffler on my truck. They did a great job, were efficient, quick and very affordable. Not to mention extremely courteous and friendly!

They do an amazing job! Really good pricing, I highly recommend

Just had full blown custom exhaust done stainless steel, soup to nuts. Sounds amazing, looks amazing, very nice welds and detail. Highly recommend.

Went in to ask a question, left a little bit later after a sound test and new stainless steel muffler. Guys were very friendly and courteous. You cant ask for anything more

Very knowledgeable staff, great customer service, A+ communications

Fast easy service. This is the only place you should go for a new exhaust. They are really friendly too!

Awesome place. These guys know what they are doing. My 2011 Camaro sounds beast now and looks amazing with the stainless steel mufflers, instead of the suitcase style OEM ones. Thanks guys!

Was looking for a local exhaust shop I could trust, Googled it and found these guys . They got me in first thing in the morning and did a custom exhaust on my VW that is flawless !The price was right for the expert services I received . All welds were painted to cut down on corrosion and turned out perfect . Sounds great guys thank you so much !If you need work do yourself a favor and go see these guys !! A+ top notch guys .

I drove down from Merrimack Nh simply because of how knowledgeable the manager was on the phone, once I was there they looked at my car right away and informed me of what I needed and the price . About 35 minutes later my car was running very quiet again and the price was spot on. I was very impressed with the way they checked for leaks with a stethoscope and painted the welds afterwards, a very clean job and a lot less than I was quoted from several shops, thank u so much u have a customer for life!!!!

Took my 16 Jeep Renegade there to get a Smooshed exhaust repaired. Had them install a Magnaflow 4 Tube in place a the OEM muffler. Great job and quickly done.

Great service, impeccable install. Highly recommended !

Luther,the best ive ever dealt with,awesome knowledge,good prices

These guys rock! Highly recommend.

Reasonable price, very good job on my car. Highly recommended

Good job
