I have a 2008 Chevy Avalanche they did a custom exhaust over a year ago for me it sounds great!! I just yesterday had an exhaust leak after the pipes they put in damaged a line the takes fumes out of the gas tank. I went to see the owner and he told me to bring it in the next morning and repaired it for free no questions asked!!! Great customer service here!!! His actual statement was "its my stuff I'll fix it no charge" it doesn't get better than that!!! Top notch service and to stand behind your work over a year later!! WOW I'm a BUBBAS customer/advocate for life!!
