Yeh you will see about maybe 10 to 15bhp with a map at the max like but it improves the ride for sure

Personally i would get a custom one made up. This is what i did for mine. I went to a local garage and had my decat made for £120 and fully fitted.

They will sort out all the pipe bending and sizes to match up with your standard pipes. You could also get them to delete the pre silencer before the back box to give you a bit more of a growl  :smiley:

I can not recommend doing it enough. Although we have different cars i had mine on the rollers before and after and with just fitting the de cat i gained 14bhp.

Problem is then mapping out the sensor etc more £££. Im going to get the middle Box removed for now .. Need to fork out for a cv joint and new discs yet :cry: dont realy have anyone around where i am that knows about the mk4s sensor problem etc so not sure they would do good job making custom one without fookin up other bits and bobs.

If i do go custom will do some digging few garages and take trip down if bit out to where i am :wink:
