hm.......no clutch pressure.......you should start off by checking the clutch fluid under the hood and work your way from there. Also check the spring that enables the clutch to pop up all the time, then u should end up checking the clutch master cylinder if all is fine. I think its definitely a clutch related problem and not the fact that you're paying way too much useless attention.
As far as header goes, it aint gonna make a world of difference for performance but for looks, it will add lots. Nomatter what, get the ceramic dc headers. SS headers will rust and turn purple and red and burgundy in about 6 months max and ceramic does a little better job of heat dissipation than the ss. 100% of ppl that own the ss regret buying the ss headers. Get the ceramic one.
