Just looking to see if anyone here has played around with swapping any of the engine internals (camshafts, valves, etc). Also what about having factory ecm reflashed or bumping timing.

Going in a 12 rtx
 
BTW I only ask because I don't want the hassle of an exhaust system and nysdec. I have plenty of traction for anything unless it gets boosted.
