Best go to the Monaro/HSV section - loads of help over there.

Is yours the CV8 or the VXR?

CV8 benefits massively from tubular manifolds and a remap. Two hole air box mod is worthwhile too.

NWJ autocare in Kent, Walkinshaw performance and Top Cats racing are good places to go to in the South.

If you are willing to travel to Newcatle upon Tyne, then AAS will make you a set of mid length headers that will fit your system. Their quality is second to one. I have had their headers and sport cats on my car for years and they are ace!

Sorry to hijack
@maccavvy I too have an x-force exhaust on an 04 with middle and rear boxes.
Was trying to work out what headers will fit onto them and the standard cats.
Assuming yours are shorty's? Did you replace the cats as they didn't fit or just to decat ?
Also, do you still have middle and rear box? Tempted to replace the rear box with a straight pipe.
Thanks

Is that a standard engine ? I think you may want to put that on SRR dyno.

difficult to say whats been done.. the manifolds are very long.. and its had a custom decat .. so difficult to say where one starts and one ends
I still have center and rear boxes yes.. but cut outs in the decats... sounds mental open..

why would it need to go on SRR dyno.. monkfish fited it all and dynod it.. and ive had it dynod myself since.. I'm good with those figures.
