I know of a guy from South Hill WA. He installed my JBA headers and Cajun bpipes. I cant remember if he charged me $400 or $500 but I do remember that it was alot cheaper then what these other shops were charging. A few days after the install. I drove down to Battle Ground WA to meet up with Joe for the Uprev tune. Joe checked it out and said.....your mechanic did a good job I dont hear any leaks. This was 2 years ago. Ol girl still runs good with no codes. If you dont mind driving the 2 hours I can give you his contact info.
