Just a heads up .... Borla makes the GM Performance parts catback exhausts . GMPP just badges them . The system that Borla sells under it's own name is basically the same as the GMPP touring exhaust.... but with the tip welded on.

I measured every portion of my stock downpipe when I had it off my car.

90% of it is 2.785" o.d.

My ZZP 3" downpipe leaked at the 2-bolt connection flange. It drove me nuts.
