I dont know about making 20 extra horspower just through headers but they would definatly be a help.Mac, BBK, or Hooker supercompetition headers would be what I would go with. If I were you when you get the long tube headers make sure they are ceramic coated.

LTs always are a better choice, so long as you can fit them into your car. I know that putting LTs on my 2000 GT was a complete bitch when it came time to tighten the bolts.

yea longtubes work best on modded engines.

It's a debate for more stock type engines but with yours def go with long-tubes.

callmecobra

what do you mean? long tubes will benefit more on any motor, stock or modded

Long Tubes, H Pipe for sound, X Pipe for power. I perfer sound.

Longtubes CAN give 20+ hp on a stock engine, MORE on a modded. Shorties on a stock motor are usually worth only around 5 hp or so.

you guys read that article in MM&FF they dyno tested long tubes vs shorties and there was only a difference of a few hp so the only real difference is sound
