I installed my headers and ORY pipe and I assure you that there are NO clearance problems. The driver side one fits perfectly and there is about 1/2"-3/4" of room. Also, the passenger side is good as well.

When I turn, gas it at low RPMS, or go over entrance ramps to parking lots, there are groaning noises.

I think it might be that the headers are slipping slightly in the Y-pipe...
But I assure you that the C-clamps supplied ARE holding the headers in place AND that they are properly tightened.

Anyone have this problem (or know what the hell I am talking about) and how did you fix it??

EDIT: The noises are coming from the Y-pipe area where they connect with the headers. The outlet of the Y-pipe is welded to the spot where it meats my "y-pipe back" exhaust system.

I would get under there and to a good inspection looking for fresh wear marks. There are alot of places that the exhaust can catch causing noises ie: torque arm, floorboard, k-member,brake/fuel lines, tunnel brace, ect.

Clearance isn't the issue.

Believe me.

They are groaning because they are slipping inside the y pipe, but those exhaust clamps are cinched down pretty damn hard.

Any ways to remedy this? Welding them wouldn't be too keen of an idea because then if I have to take them off, the ENTIRE exhaust system (headers to the tips) are all one piece.

Did you put antiseeze on all the slip fit joints? I did when I assembled that way when I take my exhaust off ( It seems like its always in the way of something ) it comes right off. I have never had any noise issues with them at all. Just something to think about. Instead of "creaking" they would be silent?

Good luck with the car.

No, but that woudl be a good idea. Guys, there isnt a leak here. It is just a metallic bending/slipping noise. ANd believe me, those C-clamps are cinched.

I am giong to get some exhaust clamps and some anti-sieze.

Any vendors sell the clamps or anyone know the part number to order them??
