I am getting ready to install a Whipple 2.3 on my 2011 GT and was wondering if it is worth investing in a set of LT headers? Are they worth the HP/TQ for the money spent or should I save the $$ and stick with my stock headers/Borla S type catbacks? Just seeking some opinions since everyone is...
Just got delivered:
Steeda frnt/rear brake upgrade, upr/lwr control arms

use a SCT tuner for sure and look at some of the different tuner shops as alot of them will upgrade your tunes for free or a small charge after 3-4 upgrades to your car. i'm runing a JLT CF CAI w/ BORLA S cat-back exhaust w/BBR 91 octane, a little over a month ago i went to a open dyno day at MC...
Since i'm single again, nothing for me but my always faithfull "STANG" wants a supercharger and it's hard to tell her no since she has been so good this year
