thank you guys I appreciate you concern and your tips. I will not pursue this in court because I live in Canada lol. we don't sue here lol i will give him a chance to make right and when he doesn't I will expose his baloney across town. mind you I should of trusted my gut going to a muffler shop recommended from Performance Improvements lol (a parts shop in Canada) next time I have money to spend on one of my expensive hobbies I will do more research. I just really thought I could trust a auto mechanic hahahahahahaha BURN.
