That's a gain of 36 RWHP and 23 RWTQ! That's not bad but we're still working on some other changes in the tune...

Thats the Evolution mustangs specs , has the 3.31s too ...anybody have a clue on how much those mods might cost .. just pieces not installed ???
Didn't find much on the 2011 but my guess is the 2010 pricing would probably be pretty close.

Off road X pipe $175
Catback $540-$675
K&N $50-$60
