Does anyone know the exhaust diameter for the pipe leading in/out the secondary cats and the pipe leading in/out of the resonator? I'm assuming the pipes that go in the secondary cats have the same diameter as the ones going out (and the same for the resonator). I'm looking at adding 4 12" vibrant bottle resonators to get rid of some rasp and get a deeper V8 note. Currently have stock headers, gutted primary cats, secondary cat delete, and stock resonator and mufflers. Going to change to supersprint mufflers too.

How did you find that info?

Magic. Actually, I wouldn't be surprised nowadays if I mentioned "w204 c63 exhaust diameter" in conversation and then saw it pop up on my phone in some ad. That happens so much now

Yeah, there's no way you used a search feature or something crazy like that.

Sounds like a good Black Mirror episode.. I have an idea...
