Lou's Custom Exhaust Chelmsford

Stopped in for a last minute appointment to do a rear resonator delete on a 2017 Jeep Grand Cherokee with the 5.7 Hemi. They had me in and out in 1 hour. Looks great, sounds great, price was proper, and they employees were friendly/helpful. This is the second exhaust I’ve had done here and both times were excellent.

Great experience at Lou’s. They were able to give me a very quick appointment when I called about my car. My exhaust pipe had completely rusted off. When my car was on the lift they showed me what they wanted to do to fix it and gave me a very reasonable quote. To my delight the car was done less than 30 minutes later. Very impressed and happy with their work and their professionalism! 10/10 recommend!

I had my AWE exhaust installed on my S3 by the team at Lou's, and I was in and out in under an hour. Highly recommend them—their customer service is excellent, and everyone there was friendly and welcoming.

I had a great experience at Lou’s Custom Exhaust! I came in with a cracked piece on my Volvo’s exhaust that was leaking, and despite my car not being in the best shape, they were completely honest, professional, and incredibly fast with the repair. They diagnosed the issue, explained everything clearly, and had it fixed within 30 minutes. What really stood out was their transparency—they not only took care of the immediate problem but also gave me details on potential future repairs without any pressure.
