Doesn't fitting the downpipe also involve removing the one cat that's left after the PPP? What happens come MOT time?
I have the PPP on my MY00, and whilst I drool over the performance gain shown by the car with PPP and downpipe on dyno.scoobynet.co.uk I would prefer to keep it legal

Here in CH the original centre section (with baby cat) gets you past an emmissions check once engine is warm 
I had boost-cut a couple of times after fitting an SS d/p. But I appear to be the exception, not the rule. It only happened on very cold days in winter.
This can be fixed, apparently, via the fitment of a 2nd restrictor to try and improve the cr*p stock boost control system. BRD helped me - and I've soon to take their advice with winter around the corner

Yes - the d/p removes the Cat - just need to replace it come MOT time
You have to make a choice legal or 'fun'
