Re: Exhaust Insulators?
polyurethane bushings are good for suspension, but poly mounts on an exhaust will transmit every little vibration to the car because they are so hard. You need to look for rubber mounts. It sounds to me that there is something wrong with the way your system is setup, I have a magnaflow catback as well on my V6 and I have no shaking or rattles.
