Anyway to make the C63 Coupe sound like an M3?

How can you make your c63 have a higher pitch? That's the sound I prefer also.
I deleted my secondary cats, and replaced it with a GT-Pro X pipe (the x pipe increases flow, and gives you that higher pitch sound), I also deleted the resonators. I'm really happy with the sound of my c63, still has the 6.2l tone, at lower RPM, but gets a high pitch at higher RPM's.

You like the obnoxious sound. Get long tube headers and delete all cats, it'll sound better than that m3.

2.) Because there has actually been a lot of discussion around the sound of the M3 vs C63 and people here (of course) think the C63 sounds better (myself included).
To be honest, a lot of sound comes from how the intake is designed as well. Get some ITB's fabbed up for this motor, with long tube headers and straight pipes and it will sound like an F1 car.
