3.5" piping from where the OEM Y-pipe would end, splitting in to dual 3". This is all aluminium, and weighs in at 12lbs. It is of course louder, but not as loud as one would think.

Maybe I need a 3" test pipe instead of 2.5
Or bring my car up a couple days before seb's dyno day in June and you can whip me up an exhaust like that one..
