I have some spintech proshootout mufflers laying around that ima install this weekend if thats the design, havent purchased the g8 yet. What is the stock exhaust diameter from the cats back?
The bottom muffler is the design I have. Also
Does the exhaust tips have a one into two design coming from the muffler?

Would I have any problems just installing a 45 degree pipe from my muffler to the stock catback as far as clearance goes? Looking at pics of the stock exhaust, I think thats how the stock system is ran anyway. 45 degree pipe before muffler
GT has one into two, GXPs are two separate tips.

HSV triple gauge pack with Calais smokers kit mod, V6 tails, debadge/rebadge, V6 door handles, AU black door trim, Maverick Man under hood strut covers, & washer and bolt kit, fully corrected paint thanks to Adams Polishes and my hard work. Built with reliability in mind with some power for those times when you need to pass or go over a big hill. Just a poser, not a racer!
Those look like 3" inlets. The GT has offset in and center out. There is a pipe inside the stock GT tips that your can chisel out to make it a true 2 1/2" tip.
I built a jig to make my mufflers, so the angle on the radius bend is more like 93 degrees.
Rest in Peace Charlie!
