    Cam, Intake, or headers with ypipe?

    I was wanting to get your opinion on what I should do next, cam, intake, or headers with offroad y. What will be my biggest gain for the buck, the headers with y are pretty close to the same as the cam.

    Headers and Y first to support the Cam & intake better.

    agreed. there are certain trends to follow when modding. You can throw a cam and intake in, but the car isnt going to run as strong as you hoped for because your exhaust is a restriction. If the choice is either or, then Id go for the exhaust first, then follow it with the intake and cam and a tune.

    Agree with the fellows. The exhaust is the first thing you should do. Gottoa remove remove the factory restrictions.

    Much appreciated, now which headers gain the most HP. I heard pacesetters with offr y gain about 20-25 rwp and are supposibly the easiest to install. However I would be willing to go through some hell if another set will gain for sure around 30 rwp. The pacesetters are pretty resonable as well. Also, is it worth the money for coated ones, ive heard it only reduces temp by a couple of degrees, and that the main benifit is they wont show rust spots as fast.

    best of the best...QTP, Kooks or Stainless Works. All stainless. Most of us go with coated because of our budgets or some other instances. I havent seen a back to back dyno by swapping from abc headers to xyz headers and picking up a gain. However, I think I did see one somewhere with qtps and comapring its gains to others.

    most LT headers are comparable for HP gains, but you should look into ground clearance and ease of install as that varies from brand to brand........some think it is worth it to get coated, some think it is a waste. It does help, but I don't know if it is worth the money or not, just a matter of opinion.
