What are the best headers? sorry, been searching all day about other stuff and dont have time to search more...figure ill just do this.

the Crawfords seem to be good since they have a 40 hp gain with their package (plenum, headers, and hf cats).
the DC's are cheap.
Nismo's are expensive. hahahaa
i dunno what else.

I have spent many hours in this topic. Everybody agrees that the Crawfords are the best. They are more expensive too.
