What Y pipe are you running. It could be hitting the floorpan.

Yeah check out the pipe and see if its hitting anywhere. Also, the little brace thing that runs under the y pipe was causing alot of noise on mine so I just took it off. You might want to check that out.

the only time the y pipe bangs the floorboard is under hard acceleration. and for the tunnel brace yea i didnt even put that back on after installing the headers because the beace wouldnt even come close to bolting back up because the y pipe hung to low.
