Street Driven Performance - Carbon Fiber Diffuser Install on 2006 Pontiac GTO
Brand spanking new Carbon Fiber Diffuser from Street Driven Performance for the 05-06 rear bumper insert/valence. When I purchased it on the release date, it was $499 but as of this entire month I've seen the price holding at $465. It's not a hard install if you jack up one or the other side.
