    Yup! Any time you mess with the up pipe/down pipe you should really tune the car. Also, some intakes require a tune as well. Hope this helps!

    Headers, intake, downpipe all require a tune. But it depends on your year as to whether you can get away without a tune. Either way you won't see any power benefits without a tune.

    What headers? What model car? What year?

    A lot of questions here...

    I'm pretty sure all of that requires a tune

    On the 2002, only the header will require a tune.

    will i need a tune

    Go to their site and look at their map notes. They support parts, not outputs in HP.

    Meanwhile you can sell the header and intake and save that money at least. Or keep the parts on a shelf until you decide to go much further with the car.

    With the Subaru intake and header you need nothing else; if you decide to go with the header -- and most likely the intake -- you will need a tune yet may not see gains significantly different to those you'd see without the intake or headers if you calculate bang/buck.
