I own a 2005 Black 5 speed GT, I have been reading this forum for a few months. It seems everybody has an opinion on what a New Exhaust, a Cold air intake, or a throttle body, will do for RWHP!!!! Does anybody have the facts on getting more RWHP, without a tune (messing with the ECU). Which EXHAUST, INTAKES, or THROTTLE BODY's, really provide more RWHP. ONLY Mustang GEAR HEADS, who the proof, (ie DYNO) need to Answer.... This thread could be usefull to alot of 05-06 STANG owners!!!!! BE COOL! BE QUICK! BE GONE!!!

Check out www.rpmoutlet.com as they dyno their performance packages and display rwhp. Your gonna need to tune via a programmer for most performance parts due to "Spanish Oak." However, I purchase my parts from brenspeed.com . Hope this helps.

All the way at the bottom is a nice package....would be better if it had an xcal2 though

You need a tune for everything.
