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.


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.

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

andy the manager is a good guy as well as the technician who did the repair. i was treated well, respectfully, and... professionally. everything was explained to me and shown to me. the exhaust pipe leading to the muffler rusted out. they custom fit a section of the pipe with stainless steel and a new hanger and took care of the joints. the price was fair and reasonable. i was in and out very quickly. i wouldn't hesitate to go here again and would highly recommend.read more
