I guess no one has a 4th gen Prelude w/ an N1 exhaust w/ a similar problem? Well, I was looking into exhaust/header wrap to solve the problem. It's a high heat wrap, that I think wouldn't hamper the performance or life of my cat-back. I know it's made for headers, but perhaps wrapping the area would dampen the clanking of the piping on the control arm? Any ideas?
