UDP or Headers?

[SilvFroCSVT]

Just wondering what you guys think would make more power... I already have an intake and y-pipe. For performance would the headers or underdrive pulley give me more power or mpg? Eventually I'd like to do them both but for now I wanna know which one I should start with. Thanks!

I think the headers will help you more, especially in the higher RPMs. I'd go with the header.

UDP pulley unless you plan on getting a tune IMO.
You could argue either way, but I always thought the headers are a big step that should require a tune to make worth the install.
UDP is just free HP from parasitic loss, doesn't need tuning.

^ that is a good point, and the UDP is much easier to instal.

Ok guys. I really want the sound and power from the headers but not if it requires a new tune. I'll try out the UDP for now and see how that helps.

Do both. What a dumb question :laugh:

You don't NEED a new tune for headers, but you can net some big numbers if you do.
