exhaust makes rattle on cold start. However when i warm it up and start driving the rattle dissappears. FYI i have a pro-1 exhaust with the pro-1 y pipe. Anyone have any advice?

 

its hitting the cross member. My fuji did the same thing and rattled at certain rpm's. Try and looses the bolts on the exhaust and see if you can raise it up at all. If you cant (mine wasnt going any higher) take a pry bar and bend the cross member a lil bit and the rattling will be gone.

 

yea mine started doing the same thing and i have the greddy evo 2 and once i warm it up it goes away...i might sound stupid askin but what is the cross member?
