Are the exhaust setups on the Bonnevilles stainless steel? If so, does this mean that I shouldn't have to replace it ever?

correct.

So much for my plan to put an aftermarket muffler on when the exhaust goes.

The muffler will go eventually. The piping is mandrel-bent stainless steel. Very high class.

I seem to sense your muffler going south. Is that what you wanted to hear?

More or less, it takes so long you might as well do it now

Well I've got my money tied up with fixing paint defects for the time being but I was planning on putting this http://store.summitracing.com/partde...5&autoview=sku muffler on when the current one goes and probably do a high flow cat at the same time and was just trying to figure out when I'd need the money for that project by. Any idea how long my stock muffler and cat should last? My car'* a 2000 with 80,500 miles on it if that helps.
**Edit** I don't know if everything on my exhaust is original equipment, I think it is but I'm not sure**

My second choice muffler is this http://store.summitracing.com/partde...5&autoview=sku

Anybody know when the muffler and cat should be expected to go?
