I have the CF cans with my setup, looks pretty good if you ask me. I think it like more than the SS cans I've seen on the 40ths. The sound is amazing for sure.
I'll try to take some pics tomorrow...if I manage to wash the car.
Also, I'm lowered on KWv3 coils and haven't had the exhaust scrape on anything...wish I could say the same for the chin spoiler up front.
