Got my exhaust replaced under warranty due to a rusting exhaust tip. I was hoping for a direct replacement but the one I got is a step up. It has a straight through design, larger inner diameter, sounds deeper/louder (Although I didn't want that) and seems to make my car run a bit better. On the cosmetic side, it doesn't have an angled tip and it only says mazdaspeed on one side. The jury is still out on the increased sound of the muffler but the slight extra performance is nice!
