Who makes a Header for my 03 GT?

[high revin]

Looking for the best header for my 03 GT Ive seen just a couple posts about headers on here and i think i have a cracked manifold and i decided to just replace it with a header.But have only been seeing them for the base models.Any suggestions?

get another stock one and port your stock one. The aftermarket ones have shown a decrease in power for the GT

Id like to see those facts hard to beleive a stock cast iron manifold will out flow a smooth runner equal length header only advantage would be the torque down low of a factory manifold.Ecs if a header is designed well for low and mid range torque.Was just curious of anyne that makes them looks as if mine has a crack in it picked up a pretty god tick.

Well here's the main reason I never installed the DC Sports header Check out this thread regarding ported stock manifolds:http://www.newcelica.org/forum...d+2zzh ... um...15089

Are the DC's a direct bolt in to replace the orginal manifold.

Those were the main reasons I didn't install mine. I suppose if someone were to port and polish it could do better.
