I have what i think is a H&S back box on my blob STI PPP. I would like a bit more noise and want to buy a de res centre section. I am looking at the afterburner vortex R 3 inch cat back system but will i have boost creep and need a remap? Reason i want the 3 " exhaust was with future mods in mind, if not i will just get a 2 1/2 centre section. What you guys think?

cheers
