My exhaust system front to back.
1 7/8" Kooks headers with high flow cats
Borla Catback Stype 3" exhaust with NPP
First had this but it was a bit on the rowdy side at WOT and cold starts.
I then installed the Borla resonator which is 2 3/4" I have to fab up some connectors to attach in the straight section of the catback.
Sounds great IMO. Still loud not quite as loud without but smooth and deep. No drone.
