Hey everyone.

looking to upgrade from my xforce headers before my next tune.

I'm thinking of going with J's racing 4-2-1 but can't seem to find enough info on them to support buying.

from my understanding the fitment is no problem, but what I want to know is whether they perform well or not?

obviously Toda and Hytech would probably be up the top of best of the best headers, but how does J's racing compare to those top end brands and to something in the low price range like my current Xforce?

any and all input will be much appreciated!
