Well... After many long nights and contemplating... I've done it. I ordered Agency Power headers and midpipes for the C63!
With them on a new tune, I should be a hairslength away from 600 crank horsepower!!! It will also sound a lot more "exotic" what with all 4 cats being deleted...
I will update with tons of pictures when they arrive and during the install. As well as dyno charts and a video of the sound. If it proves to be too loud I'll be getting an Agency valve controlled exhaust.
