"The work was completed in a timely professional manner for the price that was quoted."
"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."
"These guys do a great job for a reasonable price. Highly recommended."
"Forced the front 02 sensor in crooked and ruined the threads in my brand new headers requiring it to be re-tapped. And the nuts and bolts connecting my cat to my catback system came undone on the road. Mostly friendly people. Stupid mistakes."
"I had a car I thought I was going to buy inspected in Watertown, and they quoted me $1329.50 to replace the entire muffler system so it would pass..."
