Just wondering if anyone could recommend a good quality header for 06 wrx at a good cost. Also is an uppipe really needed since it is already catless??? Is Gruppe-S any good?Thanks for any input?
remove the first cat ,and change the down pipe ,big chance when u buy the down pipe u might get the up pipe for cheap,just to let u know its not a easy task changing those 2 pipes either ,you'll def feel a better response coming from your car.....
thanks for all of the ideas. I'll look into some of the things mentioned above. I know I probably don't need headers, but for the 10 or so horsepower gain plus they just add to that nice "boxer" sound, the money is worth it.
I agree, 2.25" is plenty. It doesn't really matter though, cause the stock uppipe isn't that big. I don't really have any proof apart from my own experience, but if you check out turboxs, perrin, crucial, autospeed, and megan racing, you'll notice a trend. They all make uppipes with a diameter of 2" or LESS. Now why would they make smaller-than-stock uppipes?
