Dropped my Volkswagen Rabbit off at 745am. They called me and were done by 830am. Great prices and very friendly! Car sounded amazing, welds looked great. They happily used a glass pack I brought in myself. Couldn't be happier with the service and results Service: Exhaust

Grade A professionals at work. I can't guarantee your experience will be as cost-effective as mine was (40 bucks to replace a couple hangers, AND, saved me a hundred bucks by welding a hole in my muffler; a great weld that sealed it perfectly), but I can guarantee they'll be honest and do good work. I'll never take my cars anywhere else. Honesty is huge to me. I'm a mechanic without welding experience. I know when I'm being screwed around. These guys are legit.

I'm in Springfield for work and had my flex pipe fall thanks to previous owner rigging. They got me in the next morning, called me with several options at a very good price. I would definitely recommend these guys to anyone. Staff has been very polite and friendly. They got the work done in no time. Dropped it off at 8am it was done by 11.
