Its the corrosion... the acid will eat them up EDIT the temps that fat back are in the 200-250 range which isnt bad at all

The acid would eat them up how fast in theory? Titanium would be great but way too expensive.
That would be hard to say but could be anywhere from a couple of months on and what the fuel is. Titanium would defiantly be out of the question for a factory/production aspect due to cost,(hell they dont even want to run stainless anymore)they prefer the junk aluminized that barely makes it 2 years

There is a guy over on the bullet that makes alum. mufflers that can be re-packed. Lots of people run them on alum. exhaust systems with turbos. My new turbo set-up has 4" alum. exhaust.
One day I will have something cool here.

I would think that corrosion would mainly be a factor with combustion liquids condensation (Ie low temps) or short duration useage by not coming up to full temp. Erosion would be from high temp corrosive fast moving gases and slower to harm. I have never heard of Alum mufflers before. I would think a Ti muffler would be doable, albeit at high but reasonable cost, even home made. Sounds interesting. And remember that alum loses a lot of strenght at even 400F, a small backfire at operating temp and I would bet an Alum muffler would open right up. Alum with a decent amount of continuous outside cool air flow I guess is needed for durability. Header wrap would likely be no-no, but you could also jet coat it inside and out (if no packing) for additional lifespan.
I myself would prefer a nice 300 series SS muffler over anything else.... would look nice , all shiney and would have a nice long life..... I need to finally replace the SS muff on my Jeep(94) with 228K on it

I've seen bikes with carbon fiber mufflers that were light as a feather and relatively quiet. Probably can't do them yourself, but wouldn't someone make them for the high dollar cars?

I know they make them for imports, I would buy them if they made them for my car
