Personally, from what i read, I doubt I'm gonna feel the difference. And also, I cannot seem to find a vid of full Challenge exhaust (street x pipe w/ slip on rear)? Does anyone have this setup? Am I gonna need a tune?? It never ends, LoL!!! Thx...
wrong forum bro... but nice pick with the challenge and with the street you won't need a tune...
