Lou’s Custom Exhaust Lynn Ma., on the Lynnway offers a wide range of automotive exhaust services at our auto repair shop just north of Boston. The exhaust system in your car or truck has progressed over time to become a combined safety and emission control system.

The exhaust system should be inspected regularly and repaired immediately at our service center if you notice any problems. The exhaust system’s very purpose is to protect a vehicle’s occupants from harmful engine gases by redirecting those gases away from the car to the outside air. The exhaust system also helps to ensure a quiet and peaceful experience by minimizing engine exhaust noises while driving in and around Boston. The catalytic converter is an exhaust system component that minimizes the amount of dangerous pollutants found in the engine exhaust. Other components of the exhaust system include oxygen sensors. These sensors monitor oxygen levels in the exhaust gases for the purpose of ensuring the overall efficiency of the catalytic converter and engine’s operation.

Various factors contribute to the wear and tear of your vehicle’s exhaust system, including your driving habits, Boston road conditions (salt, bumps, road spray), the type of vehicle, and the age of the exhaust system parts. Some warning signs that may indicate vehicle exhaust system problems would include loud rattling noises heard during vehicle start-up, acceleration, braking, and experiencing drowsiness while driving.

Lou’s Custom Exhaust offers complete automotive exhaust repair and service at our Lynn repair service center. Our mechanics are considered the exhaust system specialists in Lynn ~ Boston and offer complete exhaust system repair and replacement services for all foreign and domestic cars and trucks.

WE SAVE YOU MONEY

Rather than replace your entire exhaust system, We have the ability to diagnose and replace only the failed component as opposed to just replacing the entire exhaust system.. Saving you Money.

We stock everything necessary to fabricate a small section or an entire exhaust system using only the highest quality parts. Because we fabricate everything in house, We cut out thte middleman. Passing the savings on to you.

Awesome work on the rear muffler it had a whole on side so less power for me to drive. The price was right and didnt... take long just about 30 mins. Thank you i will be coming back for my other car soon.Went back 01/08/2024 for the 07 ford expedition, needed a appointment and the guy Andy very generous telling every detail of the problem and i had no clue of there were multiple leaks on the end of my exhaust manifold and the pipes haha so he replaced my Driver side exhaust manifold and the hardware that attached to the side engine both sides which was needed and he gave more welds so theres no more leaks anywhere plus he also gave me a better price than other places so i was happy with his work so the price is good under nine hundred so i paid no problem and my truck runs so smooth now. Thank you so much i be back soon for my next car.read more

These guys are the best around! They did my flow masters at least 6 years ago. Today, my exhaust sounded funny. I... looked under my truck and saw my exhaust hanging. I called at 4 pm to ask about any availability for tomorrow (Saturday). He said to drop it off first thing in the morning. After we hung up, 10 minutes later I got a call back from Lou's. They asked me to bring my truck right in. Remind you, this was 4 pm. I brought it down and they welded my exhaust back on, free of charge! I was outta there by 5. I am so appreciative of these guys. Anyone who needs they're exhaust done NEEDS to go here. They are super nice and caring about your needs. Everything is explained to you in plain English and time prices are unlike anyone else. If you go anywhere else, you're a square!read more

Recently, I needed work done on my exhaust, which the dealer was going to replace for $1,500+; however, luckily, they... recommended Lou's.I called once I got home, and even over the phone they knew the issue and how easily it could be solved - for around $200. They scheduled an appointment ASAP so nothing would get worse, and I arrived no more than 30 mins later.They fixed the car in under an hour, showed me the process and explained what was going on throughout, saved me over a thousand dollars, and the car runs great now. I WILL BE BACK when something inevitably breaks again.read more

Andy and his team are among the best professionals. I work at the airport and live in Lynn. I went to several places to... repair the car exhaust. It was very loud, but after searching, I was able to find this best place and the best professionals in car repair here in this place and at an unbelievable price. Thank you, Andy and all the employees. In this store, the dealings are very wonderful and the words are very wonderful. I advise anyone whose car is idle to come to Andy and his professional workers.read more

Andy and his team are hands down top professionals. I work at a dealership and my tech couldn't modify my magnaflow... front pipe to properly install. Lou's installed an extension pipe to move the cat converter. Sounds amazing now. Best exhaust shop around. Thanks again guys. Don't have to listen to the wife complain about the clank anymore.read more

Called and spoke to Andy and he took my vehicle in the same day. I previously went to another shop and was told I... needed an entire exhaust system. My son recommended Lou’s. They diagnosed my problem and even showed me. It was hundreds less and they fixed my problem in 20 minutes while I waited. I highly recommend this shop!!read more

I had brought my volkswagen cc in today, with what i thought was a massive exhaust leak... dropped it off at lou's... custom exhaust in lynn and he said he would take care of it. He let me know that it was not an exhaust leak but it was my turbocharger and it was faulty. Every other dealership said I would need a new turbocharger which would cost upwards of 3,000$ with parts and labor. He calls me back about 30 minutes later and told me not to pick my car up just yet, he told me he is researching the turbocharger and thinks it may be fixable. He ended up fixing it, and charged me an awesome price my car runs perfectly and he saved me a fortune! Above and beyond service and this will always be my go to place for myself and for others who need work!read more

Had a great experience from start to finish. Called on a Saturday told it was too late in the day to make same day ... repair. Told to bring in on Monday morning. I brought it in Randy explained the issue, gave an fair estimate and got the work done on time. Randy also went further by assisting with an issue not related to the repair work. I was referred to the shop by a trusted mechanic. Randy and team came as advertised!! I’d do repeat business and refer a friend.read more

I recently had the unfortunate experience of dealing with Lou's Custom Exhaust and I cannot express my disappointment... enough. Not only did I have to go back to the shop twice, but they still managed to get the exhaust system wrong both times!The incompetence displayed by the staff at Lou's Custom Exhaust is beyond alarming. The lack of attention to detail and disregard for their customers' needs is simply unacceptable. I cannot stress enough how unprofessional this place is and I would strongly advise anyone looking to have custom exhaust work done to look elsewhere.In conclusion, my experience at Lou's Custom Exhaust was very disappointing. Their inability to provide even the most basic level of service, ordering a cat back system and install it, has resulted in me being out of work for two days and 4 uber rides. All I gut form them is sorry we can order the right system the 3th time, unbelievably a custom shop that can't even order the right parts. Do yourself a favor and stay away from this establishment.read more

Guy on phone was rude. Inquired about installing an exhaust on my car if I brought in the exhaust and was willing defer... on the warranty and just pay for labor but was refused. Don’t see what’s so hard if it is a brand new in box exhaust andI just want to be charged forLabor and I’m not worried about there warranty.. Was going to give them my buisness even if it was just for instal andLabor but i guess they are more interested in overcharging for the same exhaust that you yourselfCan buy online. Went to there Revere location very long time ago and had no issues. Called signal in Salem and they had no problem installing the exhaust. AndIn there response belowI go to many businesses and I don’t always post every experience but mostly the bad ones so people aware of shady businessesLineLou’s custom exhaust. Other businesses that I have spoken too saidThat Lous custom exhaust has been ripping people off for years so I think I made the right decision by going elsewhere. Zero stars for you shady Lou…read more

Andy was straight to the point after getting the runaround at Honda anc bay state and everywhere else. Was expecting to... need a loan because my car sounded like an airplane. My car was fixed the day I brought it in and was a fraction of the price i expected to pay. Also a plus when you leave valuables and money in your car by accident and the owner made sure all my things were there! Highly recommend!!’read more

First and foremost, would love to say Andy is the best! Great service. Extremely helpful staff and mechanics. Really... gives you the actual knowledge needed with what’s wrong with your vehicle. Would give 10 stars if I could. The vehicle I just recently purchased had a whole bunch of pipe and other problems. Had Lous custom take a look at it and came back 2 days later and they managed to fix what needed to be done within the same day. Highly recommend! Will be back (if necessary) lolread more

Great service and friendly staff. I came in to get a new muffler installed for my car, along with some other issues in... the exhaust system. The staff explained and even showed me what needed to be done. Everyone was very attentive and professional that there was no room for miscommunication. The price was also very fair. My experience here was so positive that I will definitely be coming back.read more

Had a gasket fail on my stock Ram, this caused the exhaust to leak and wouldn't pass inspection. Contacted Ram although... my truck is covered under its warranty they couldn't fit me in till the end of January. Walked into Lous today on my lunch break hoping I can get my truck fixed by the end of the week. Nope I was completely shocked and suprised, they pulled my truck in put it on the lift and gave me some satisfying options. I choose to have a repair and muffler done.(I wanted a better sounding exhaust). I asked the manager when I can come back for the repairs and upgrade, at this time I'm stoked about the reasonable price but when he responded, do you want to wait an hour? I was blown away, talk about great service and affordability! Glad I made the vist, you will forever have my business! Highly recommended.read more

I have been a Lous customer since my days when I was in the import scene. We mostly dealt with the Revere location at... the time. Today I needed some repair work on the exhaust of my daily driver. Right away I was greeted and asked what the issue was. Lucky for me it was not that busy and my car was brought in and looked at. The best thing about the place is that I was presented with options with zero pressure. I decided on what was best for me and proceeded with the repair. One thing I took note to is how clean the shop is inside and out (look at the photos). I was observing the guys working on the cars assigned to them and they where all taking note and making sure their work is lined up perfectly before welding the part in. I'm glad I came here as I also took note from other customer reviews. Best of all is that it's in my city not far from anywhere around here.read more
