cheap DE headers

i'm not sure if there is an issue with my setup, or my previous header/exhaust combo was just really good to start with, but yeah, lots of money for no gain up top =

I'm really hoping that the intake or cam gear settings (currently +2.5/-2.5) are bottling it up.

if you have a set of x-force headers, and a 2.5" exhaust, dont bother upgrading if you have a similar setup is the motto I guess...

This is not a good look...

I'm sorry that they didn't seem to perform as expected for you; I hope that mine do though.

I wonder what else is holding these back?

What's it like to drive? Did you gain any torque?

^^^ that sucks dude

i have dealt with cheap x force crap before, and its pretty good gear for the price

your power band is a lot more linear now, you have got rid of that hole from 5k to 6.5k

yeah I expect the car to be faster as thats pretty much where the revs drop to on gearchanges, but was hoping to carry a little bit more up top.

I guess going 3" didnt provide much gain either over 2.5/2.25"

LoneWolf what kind of timing do you have in the higher RPM's? I found that you can run 28deg so far maybe lower with the 4-2-1.

didnt check, tuner did play around with both timing and afr's up top to try and get more power, no go.

How much for your xforce header?
Is it portmached?

xforce retail for about $450AUD brand new
yes it was port matched to the VE.
