Will these header pipes give some considerable increase in performance?
My mods are PCV + O2controller,Leovince X3,DNA stage 1+2
I want to purchase one more mod to give some more Hp/torque to my Xtx and i'm between a camshaft or the OTR header pipes but i don't know what to choose between these two...
Which do you suggest me to choose?
Cheers
