STi 6 - Exhaust centre section swap
Will putting a centre section (with a cat) back on after the cars been mapped (by AndyF) for a full decat exhaust cause any problems? Will there be any big loss in power?

Use a UK centre to get through MOT. Normal driving will not a be a problem with the cat in place, but contact Andy to confirm. Issue is that you introduce back-pressure with cat; depending how agressive boost profile is you may run into problems if you find you have to warm the cat up to pass the MOT (warm it up = rag the nuts off it for 10 mins....). Chances are, boost will simply drop off a bit at WOT with cat in place, but check to be sure.

Might get one of these then unless I can find a friendly MOT centre. Can someone PM me if they know any in Buckinghamshire?
