I got my long tube headers, h pipe, and exhuast and when I take turns or go over bumps I hear a thumping noise under my car. It sounds like the pipes are banging around on something.

is this normal. What wold be wrong?

it can be fixed. Usually the cat-back portion ends up hitting the body or the suspension towards the back where the pipes curve up and over the axle. You just have to loosen the bolts and adjust it to get enough clearance. I had to do this twice after install before i got it right. (when you have the car jacked up and the wheels are hanging, there is more clearance than when its sitting on the ground, so its trial and error). Good luck!
