need info????
which is better a mac header/y-pipe combo or a pacesetter header-y-pipe combo, both are cearamic coated and without cats
are the egr and air vital to the headers or can i just buy one without them considering my dad owns a inspection station, and will it give my car any problems if i buy headers without them like check engine or reduced performance

also how can i remove the whole air and egr thing from my car, nvm the second part of my first post i jus found some info:
EGR - AIR - O2 Sensors - Motor/Tranny mount FAQ!
Ordering some headers? Wondering which options? Headers banging the floorboard (motor mounts)? Answers below....
EGR - Exhaust Gas Recirculation - Emissions controll device. Injects exhaust gas back into manifold for re-circulation. Came on 98-00 f-bodies only. Never on y-body or 01-02 f-body due to revised camshafts.
Removal Pro's:
Cleans engine bay, less weight, easier to work on things, pure air > burnt air.
Removal Con's:
Could cause you to fail "visual" inspection depending on how strict your state is. Removing without tuning work will cause Service Engine Soon (SES) light, dead giveaway to inspectors. Sniffer tests could be a problem as EGR cuts down on NOX gasses. Blockoff plates for exhaust manifolds required unless using "race" headers.
Example)
- Texas "visual" - pop the hood, don't look at anything, close hood, $12.50.
- California "visual" - pop hood, tech LOOKS FOR EGR, kicks you in the nuts.
AIR - Air Injection Recirculation - Emissions controll device. Injects fresh air into the exhaust gas before the cats. Helps them heat up to reach "emissions light off" faster.
Removal Pro's:
Weight, clean bay, no more annoying sound on startup, spare rubber hose to use on other stuff.
Removal Con's:
Only worry about VERY strict visuals (read: California) causing failure. Sniffer test can only tell before car is warmed up. After car reaches operating temp, the AIR pump shuts off and becomes useless. SES light will come on if system is removed unless codes are tuned out. Blockoff plates for exhaust manifolds required unless using "race" headers.

Both are good sets of headers and will be close in performance, but the Pacesetters should offer you the best gains. They also offer very good spark plug access which will make future vehicle maintenance easier. Also, the Pacesetter long tubes offer very good ground clearance.

do the LTs...
and do yourself a favor..when you have the manifolds our...put in some poly motor mounts...should virtually eliminate clearance issues..ie banging the floorboards.
it's cheap and easy to do when the exhaust is out...but a PITA when the manifolds are in and probably nearly impossible with LTs in.
