"The work was completed in a timely professional manner for the price that was quoted."
"I had a Magnaflow resonator and stainless steel piping installed. Clean and seamless welding, and reasonable pricing. My exhaust system sounds amazing. I receive a lot of compliments and head turns. I'm considering them again on my next vehicle for a cat back install."
"Great service -no appointment necessary- in and out in 30 minutes on a Saturday and cost was way less than I expected- would highly recommend!"
"I had a small leak in my exhaust system and I stopped in at Lou's. It was lunch time and I interrupted the staff. They said no problem ,diagnosed my problem,welded my small leak and was on my way in less then a 1/2 hour. Great service and a very fair price. Highly recommend!"
"These guys helped me out a lot. Need to go back when they are opened up again to adjust something but very happy with the work."
"Fast. Fair. Decent job. Would go there again for sure."
