Are the tips rubbing the rear bumper and causing the Vibs?
|i can't say for my z, i had the same rattling problem. let me guess its when you initially step on the gas, or turning while changing gears, if these are correct your catalytic converter is broken. since you now have a higher flowing exhaust you are now able to hear the catalytic rattle as opposed to before with your stock, you could not hear it.|
Borla is notorious for rattle because on one of the hangers is at an odd angle. I know you said you checked this but i have fought with mine a few times until i pounded it straighter. Get under the car, look up and you will see the rubber that the hanger fits into, the hanger had a tapered end, on the rubber there is a metal bracket that does tend to rattle against the hanger, (it is on the front of the hanger not the tip that goes through the other side) i have layered electrical tape to muffle the noise, do not use a rubber hose, it will create an obnoxious squeak on turns.....
It may not appread to be rubbing but check around the forums, you might get a picture that shows exactly what im talking about, try to use the fix and see if it fades....
