I recently bought Mac longtube headers for my Trans Am. The problem is I keep getting a hard bump/banging underneath the driver side after installing them. I bought a 2.5 mufflex bump stop and the problem won't go away. Do you guys know if I can buy or do something else to fix the problem? Please help, thanks.

So what is the mufflex bump stop for? Will I still need it?

if you're doing poly motor mounts you will not need the mufflex bump stop...
