my brother would bang when he was in high RPM and shift (racing) so he had it welded, that fixed the problem. Hopefully i will not have that problem as i will installing LT soon

Poly or solid motor mounts should cure the problem. I figure that since you are under there why not get some for the transmission as well.

You can always get some hose to put above the pipe?

Lol, so many people do that too. I would be afraid I would melt it with the 800rwhp I am laying down!

Do you have ANY clearance without the motor running? My y-pipe had no clearance after I installed the poly motor mounts because the mounts themselves raised the engine/tranny assembly 1/2". I removed the y-pipe and crushed it in a vise about 1/2" total. After reinstall I have about 1/4" of clearance and no banging issues what so ever.
