I really do apologize if I am beating a dead horse here. I am about to pull the trigger on buying some mods for my 2010 SRT8 6SPD and contemplating buying an exhaust as well. Problem is on the exhaust I hear that the change would be strictly for sound with little to no performance gain. If there is no performance gain then I would probably just do a resonator delete. If there is anyone out there that can tell me some certainty it would be greatly appreciated.
