So how exactly would you describe the tone? Does it sound like an American V8? Or do you KNOW its an M3 or german sports car...? You can never tell through videos thats why Im asking..
Either way, I am 99% positive this is the exhaust for me. Any closeup shots of the tips PLEASE? I am dying to see how far they stick out with the diffuser in place!

no cel because you still retain the factory o2 sensors. if you look at the pic of the system you can see where the o2 sensors mount
