0-60 and 1/4 mile times

[91 Celica St]

yea any car nowadays realy wont get shit from basic bolt ons, there already like 2-1/4 in exhaust and already namdral bent headers/exhaust and all that good junk, ull see more from a cold air intatke then from a header and exhasut combined...

haha ive seen a dyno slip of a 350Z w headers and exhasut that put out LESS tourqe and the same amoutn of Hp but at a latetr RPM,

the toruqe in the low end went to shit and the Hp was crap till high end it bascially makde to car slower...not to mention nowadays u could just spend the money on something of equal or lesser cost and get more power outta it, like a flywheel or underdrive puly
