Top of the list when it's time to upgrade.

On e85 though your cooler should be more than capable

I think Joe has seen up to 470kw out of the stage one pw cooler but that was on kevs (process west) car I think that had a built motor ?

Don't go the nizpoo zorst.....I hate mine. Always friggen leaking at the v-bands. As you prob remember, I have the valve fitted and it sounds like sh it when its idleing. 3 grand on a cheap ass, not well made exhaust is fine if you win lotto otherwise look at the other options out there

My stage 1 loses up to 1/10 at the track once warm (in 30+ degrees) I can live with that. I'm upgrading turbo early next year and the stage 1 will stay. I'm not cutting the car.

lol if there was a better performing exhaust on the market I would buy it. I think for sound and flow it's probably still the best it's just a shame the quality isn't better. After talking to one of the other forum members he has recommended a better quality v band. So I will probably get Joe (cms) to order them when he orders the exhaust. I think I will give the valve a miss and just stick some sound deadener in the boot

and under the back seat......

-------------

Obviously I can't back this opinion up with any specific data but having seen and heard what the 4" Xforce is like with the GTX..76 and driven one as well, I would honestly have a serious look at it.

Save a bit of coin that you could put to other things.

Lu82, You got a link or name of better V-Band?

It's a Cummins part. Will see if I can get the part no from the bands tomorrow.

Found the spare I've got.

Cummins Exhaust

4" V Band

Part no. 89520K

I ordered them from RP Wallis wholesale Sydney, they're in Wetherill Park.

Would avoid going to performance shops as they charge over $100 for one v band. From truck part stores they're around $35.

Also the Cummins v band has a shorter bolt so you need a decent set of multigrips to start closing it to get the nut on.
