Well thanks for the advice, I'll try to check that this weekend. I'm worried that it won't be that because while i was going up a speed bump a little bit side ways, when the right tire went up I would hear the noise on that side, then when the driver's side tire went up then I heard the noise on that side. Oh well, I'll check the cat and see if that is it.

BTW, yeah I have a 98 vr6 red on black leather, the only mods that I have is the neuspeed pflow kit, the garret chip and the A4 conversion headlights from hella!!!

thanks again for the advise. I'll let you know if it was the hangers.
