I have a stillen header, 2.25" cat back exhaust with a magna flow muffler. I have a resonator and the piping is compresion bent. It sounds like a dirt bike when I get on the throttle and I was wondering if I should either get a bigger resonator, or a new muffler. I am going to get mandrel bent piping as soon as I find a place to get it. My muffler is preddy ricey cause I bought it when I didnt know any better, paid 200 for it and I think I got ripped off.
