so i went to the local track friday. i have an 05 gtp with k&n fipk intake, powerlog, ported rear manifold, 180* tstat, and 3" downpipe. i found there an 04 comp g with headers, a custom tune, intake, open pipe before mufflers, 1 range colder plugs, and colder thermostat. i figured it would be one hell of a race. So we line up our launch was really close and i just walked away from him. i held about a 2 car lead on him all the way down the track. He ran a 14.92 to my 14.70. so i kinda figured out that headers arent really that great.
