I will soon be in the market for a new downpipe/de-cat etc but i need some advise as to what to go for.
I have the p1 back box but is their anything better out there?????????
The object is as much power/torque gains as possible.

jay.

 

Tried a scorpion full system - but took it off cos it sounds like a cats stuck in it at 5000rpm!

 

I spoke to prodrive extensively about this........and although it may be biased,I've heard similar from other 'tuners'...... The P1 backbox is probably as good as it gets...... any changing the backbox for 'more horses' will be almost futile 'cos the gains therafter with a downpipe (or anything else) are only (at most) going to be a few horse power.......
IMHO - stick with the backbox you've got.....and to be honest what sort of BHP improvement are you looking for this side of a cylinder rebore ?????? A downpipe will only give you another 15 BHP .....??

Curious........!
