aluminized vs stainless
Stainless steel is the better option, as it often looks better (if polished), but the main reason is it's anti corrison properties. It should in theory outlast the car. But you do have to pay to get it.
The alumised one, should outlast a regualr mild steel component such as a STOCK exhasut. But it will eventualy corrode and will need replacing.
I say if you have the money go stainless, unless you plan on getting rid of the muffler or car in the near furture, then it really doesn't matter if it corrodes.
How long did the stock one last? Remember that was just mild steel.
