2000 Boxster Exhaust Mount failure

[Pbastian]

So I am back to square one.

Went back out on the track yesterday. Spun once, stayed on the track. Went off track on another lap, but only slightly so, and certainly not in rough terrain. Got home before I noticed that this damned thing has broken again. Bolts are sheared off. Wondering now if the spin causes enough lateral movement in the exhaust system to shear those bolts, or if I hit something when I went off the track on a subsequent lap. Unfortunately, I did not pay enough attention at the track to correlate a specific event to the mount failure. BIG problem here is that the repair requires removal and welding. I'm looking at replacing this whole behemoth of a muffler with something lighter, and easier to mount. Any suggestions would be appreciated.

Man I'm no expert but I stayed at a Holiday Inn once. LOL. I have replaced my entire muffler and hanger system to run an "S"......moment of reverence... and it is an extremely robust system. As you probably know the entire engine, trans and muffler are designed and move together as one unit. with the muffler being supported between the upper and lower supports which attach to the mount bolted to the tail of the trans. With that being said IMHO either the bolts are now weak from welding or the engine is moving too much and the muffler is hitting the body somewhere? How are your engine and trans mounts, any evidence of the muffler tip contacting the body? Is it possible to take some more pictures of the hanger system? Good Luck
