Forgive me, I know that this question has probably been asked dozens of times but I want a meaner sounding kompressor without making it sounding "Ghetto". From what I can see (and please correct me if im wrong) there is the main catalytic converter right under the headers, then there is a second cat under the car followed by a resonator and then the muffler. So far what im thinking about doing is leaving the first cat how it is, replacing the second one with a Magnaflow Hi Flow cat Part #53005, deleting the resonator and placing the 2025i Aero Exhaust. I will put a video on youtube once this is done just to show the end result. My question is this: I am really tempted to replace that first cat with the hi flow, delete everything else down the pipe leaving just the 2025i exhaust at the end. Does anyone know if this is a good idea or should I not even mess with that first cat?
