Ive got a V7 uk sti prodrive(without ppp) and im hoping to replace the standard STI system with something with a bit more noise. Im thinking of the blitz cat back system but am unsure about the de-cat part. Can i get hold of a replacement cat (ie like the one supplied when you get the prodrive ppp) and does anyone know of a supplier or will i have to bite the bullet and go for a de-cat.

Cheers
