Just a FYI, and not necessarily a recommendation, but in a recent thread, it was mentioned that if you have the dealer replace your exhaust with OEM exhaust, it will be warrantied for as long as you own the car.
Any decent exhaust should have the same. I believe Baktash has said the same about his.
Yup, ours is warrantied for life, including the catalytic convertor and the muffler
