Quick Exhaust Question
Grand prixs; does the 3.8 catback systems work on the 5.3? I seem to remember the answer being yes, but a hanger has to be added?

a 3.8 exhaust system has the same routing HOWEVER the piping goes from 2.5" to 2.25" at the Y, i was wanting to upgrade to GXP exhaust on my GTP just because its bigger then the oem piping, yes there is a hanger position change difference between the systems as well, its worth it to swap if your putting the 5.3 catback on the 3.8, but not visa-versa
