Before I spend money on an exhaust system, I want one that's completely stainless and does NOT rust. That's half the point of an aftermarket/performance exhaust!

The other options include aluminizing or ceramic coating... The former works well, and the latter is supposedly better... However, I'd had two exhaust systems ceramic coated and either the shop sucks (most likely) or the process is bullshit... Both rusted in spots where the coating was too thin or didn't adhere properly.
