The only modifications I lack from being able to go to Stage 3 is the downpipe and a cat back exhaust (Cobb recommendations for Stage 3). The previous owner removed the muffler and added some new tips to the exhaust. Will I get the full potential out of the Stage 3 OTS with just an aftermarket downpipe and a stock cat back?

Yes. Catback doesn't do much it's mainly just the DP that gives you the power gain. Obviously the catback will add another few HP, but it's hardly anything but a nice sound.

edit: Reason being that our exhaust is actually really good, other than the downpipe.
