great, removed the cat and the centre box. made a very noticeable difference to acceleration and not much difference in sound. the whistle from the turbo on take off is slightly louder but it sounds good. really woke the car up, more free flowing. i definitely reccommend it!!
only downside is i think over there you need the cat in place for the mot? you could just jeep the cat in place and gut the insides though. i'll try and make a vid of the sound

I already have a De Cat on my 5 cylinder AEL Quattro TDi but I'm thinking of removing the centre box as well. Just hope it will sound okay.C4 A6 AEL avant quattro: daily
