I have been told, and have noticed my self a bad smell coming from my car. Its my cat I have been told, so what I want to know is whats my best option to do with it?
its on an ae111, I want to replace the cat with something so that I don't get a tinny exhaust sound.......
whats best option, 1 resonator? 2?
Will I get better performace after such an undertaking replacing the cat with the resonator(s)?
Cheers for all advice!!
