Bolt-On Basics: RSX Type-S
i have a PWP 02, so you know the soot shows. I have the Aspec rear. I just installed an HKS Hi Power exhaust and after a week, I have black soot on my rear bumper. PWP. I cleaned it off and a week later, same thing. I have stock hangers BTW. Also, I'm not in VTEC all the time FYI.
