Default C6 GS NPP Exhaust X-Pipe?
I have a 2013 GS that came with the NPP exhaust. Did an x-pipe come as part of this option package, or, did it come with a h-pipe? Thanks.

All ls3 corvettes (08-13) came from the factory with an X. 12-13 ls3 corvettes came with 4 catalytic converters. 08-11 came with two converters but GM has done a recall to add the 4 cat system to the 08 and 09.
