STB's are a project?
They take like 10 minutes to put on LOL...get the GMPP kit like stated above...bigger sway bars and the rear trailing arms make way more of a handling difference than STB's
Awesome.
Open Cone is FTW...as long as your modded...its not the best idea for a stock car...maybe around a 3.4" setup...but its your call...open cone does give better throttle response and more blower whine...which is win.
Open Cone is the way to go. You will get the most out of this mod with a reprogrammed PCM and a colder thermostat.
merged your threads since they have the same subject...
