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
