headers vs. ported exhaust manifolds

OK. i have a 2000 gp gt and i dont have 700$ to spend on SLP or TOG headers. ive heard something about Ported Exhaust Manifolds and was wondering if they are worth getting. i have also found a place to get headers for cheap but ive heard bad things about there quality. so i was wnodering what would be the best thing to get for the money. here are liks to exhaust parts i was thinking aboutt getting

Headers about 25 hp. Ported Exhaust Manifold 8 - 10 hp. Save up some more money and get the headers.

That's really a good question. SLP and TOG headers are good but expensive and they have their minor problems too. Both of them are a PITA to put on DIY. I went with SLP. A friend of mine went with TOG but he gets weird vibrations because it touches the anti-sway bar. We had to install insulation.

Don't know much about the S&S headers nor anyone that has them. Price sounds good at around $350 - $500. I know they are popular with the 4 bangers. The ceramic coated one is nice at least in appearance. What have you heard bad about them?

He's got a Gt not a GTP, so i dont think he'll see that much of a gain w/ the togs. Maybe save the money and put some rockers on the car.

Well excuse me Rip! Maybe I should rephrase an say "up to a possible". :biggrin: BTW - Nonetheless, I've seen GTs benefit from headers. How much he gets will be based on the totality of his exhaust mods. Headers aren't just for us big boys with GTPs. :lol2:

The rockers are a good suggestion.
