    Great work, great price, quick, only do what's needed. Super nice employees, friendly, hated working and respectful. Like cracked from fatigue, they fixed it and added a flex joint so it won't happen again! I wouldn't go anywhere else and all the Lou's locations are just as good.

    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.

    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 Lou's 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!

    I'll 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 Lou's will get me fixed right up.

    I had never heard of Lou's until I posted a short video of my exhaust leak online. More than one person (including a mechanic) had suggested Lou's, 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. It's no wonder these guys have great reviews.. They know their business very well! Thanks guys.
