Scorpion Pre-Cat High Flow Down Pipe

Anyone used one of these before... and is it worth it...?
Ebay Linky...

Yes I have one fitted along with my Hybrid Turbo. Currently I am running a BSR remap so I need to get a new map to cover the additions I have done to the car to see if it makes any extra power. Quite a few of the guys have just knocked out the stuff in the pre-cat but I am sure that will cause turbulence so thats why I went for the pre-cat pipe. The exhaust sound has improved since the fitting so thats a plus

I have one and got 158bhp before a remap with this and a decat so id say it was worth it

I've got one too. Doesn't seem to have made much difference on my rr'd results, but it felt a little better out on the road.

Are they straightforward to fit....?

The garage that fitted mine took 2 attempts. It was leaking on the turbo side after they first fitted it. They told me it's a ***** to get to, that's why i left them to do it rather than attempting it myself.
Also with mine having the Dpf fitted, the probe didn't fit as the Vectra's probe is on the opposite side of the hole in the pic at the top of the thread and the wire doesn't reach that far , meaning the garage had to source a threaded bung and tie my probe out of the way. It didn't cause any error messages as my Dpf software has been deleted.

shame that it is only for the 16v engine
i have the 8v 120hp engine

are there also pipes like this for the dpf replacement?
instead of smashing the inside out the dpf
