has anyone tried this system? i've been considering an aftermarket system with a hack/crossover like this, pre-muffler, and this looks fantastic. i know GMG is quality, but i was curious if anyone here had tried/heard this system firsthand.

I was curious as well. I have the the cargraphic race headers and 200 cell sport cats with gundo stock cans. Looking for a more aggressive sound.

Have you talked with anyone at GMG about the difference between
GMG 997.1 WC Muffler Set
GMG 997.1 Carrera S WC Sport Exhaust
