Hello all, this is my first time on this site and I need some help. I have a 2003 Boxster S (great car). It makes a buzzing rattling noise coming from the underside of the car on the passenger side. This noise seems to be coming from the exhaust pipes. It is especially worrisome and loud when I back off from the throttle at low speeds. I had the 'heat shield' tightened, but that did not fix the problem. Any incites as to what it is and how I can fix this problem. Regards. Compass1.
