yeah i was thinkin about doin the same thing. i have k&n SRI and magnaflow exhaust but when i went to a shop to do it they (audi, wv porsche spec) recomended i didnt.... so i decided i'll just go with hi-flow cats and resonator.... maybe even do 2.5in piping. not sure tho cuz idk if i'll s/c...

 

I know what ill do. Ill take off the resonator and put on a glass pack in its place. I heard that is an alternative to cutting it completely off.
