I have a gurgling sound whenever i accelerate my car, along with a CE light. It has a full exhaust system, all aftermarket. I went to my mech today to get it checked out, and he said the reason for this gurgling sound, and the exhaust smell from the engine is because my "flex pipe" on the exhaust system is pretty cracked/busted. My car also is very boggy since this problem arose. Anyway, he said this flex pipe (or up-pipe as i have found it to be called as well???) is pretty expensive. I was wondering is anyone has had this problem, and how much it cost them to fix? i know being aftermarket itll be more than stock, but im looking at ball-park figures here. He also said i can drive the car but to be easy with it until i fix it. Any links to sites are appreciated, and any comments or anything on this would be helpful! thanks.
