I have a leak coming out of my flex pipe on the y-pipe. im not really sure what i should do to fix the problem, as i dont want to mess up the manufactured catback. I've heard of people cutting and rewelding another flex pipe, but im kinda scared to cut into my HKS exhaust. It makes a loud raspy sort of noise on rpm's and when you let go of the throttle. Does anyone else have this issue?

 

anyone??
