Just wondering if the stock tw exhaust is supposed to be repacked with fiberglass periodically? Don't see anything about it in the service manual.

My 89 had some wisps of packing in it, but people who should have known said the TW never had any. So I tried wrapping the core with wood stove gasket held in place with piano wire, and then packing from car mufflers, but it never stayed in place well, and didn't do as much a I had hoped. I would be glad for other's success stories.

No, the stock TW exhaust does not have any packing. However, if you want to quiet it down a bit, you can wrap the spark arrestor with muffler fiberglass (long strand type), then wrap it with stainless safety wire to keep it in place. I've been doing this for 7 years now, replacing it every two years due to carbon build up. Never noticed any performance loss. :cool:
