Thread: How to install headers: The easy method

Trust me.. I put in a set of SLP's through the top on a W body once. That was enough for me to look into better methods.

Instructions used to be..
Get 3 cases of beer, 50 gallons of vasoline, couple of ratchet straps and a crapload of time on your hands.

Thanks for the detailed instructions!!! My son and I are planning on cold air intake and down tube this summer but not sure about headers. Do they add much performance on a stock motor? My neighbor has a 97 GTP with intercooler, cam, chip, small pully on SC big pully on motor, built tranny etc. and claims that headers really dont do that much performance wise until you get into some major mods like he did. He claims a stock motor will benefit greatly with intake and an aftermarket down pipe and headers are not worth it until you get into some major sh*t. I don't think we will get into faster pullys or an intercooler becuase then the trans will have to be beefed up. Just want the motor the breath better, gain a few horses and maybe get some better mileage. Thoughts on headers or not?

Thanks

SD headers will do about the same as a plog and downpipe.

SD headers are $200ish

Plog (no longer on ZZP site?) were ~$200
Downpipe was at least another $90

Maybe they don't add much, headers don't take anything away either. Sure you may lose a little low end, you'll still be able to beat the trans and smoke tires from a stop. I say..what are you losing, spinning is spinning and that's not winning.

A downpipe only helps a bit with the u bend restriction. Ask your neighbor about the front manifold restriction. IMO it's the biggest restriction on the motor, exhaust wise.
