I plan on parking my car in a week or two and when i do i am going to switch my exhaust. so i will not need my stock y-pipe to dual cat converters which flows into a 3" flowmaster system with single exhaust pipe that comes out on driver side. I don't remember which flowmaster this is but if you look up the one for a dual cat setup it's the one. it sound really good.I am not using it because the dual cat setup will not work with my headers. Not sure what it's worth so make some offers. (located in buffalo NY and will not ship).
