The CAT is part of the MOT I think.

Hi Rusty!,
I was just wondering if anyone has had any previous experience deleting both the centre silencer and back box and what kind of sound they got?

Hi..

Ive just had a full 2.5" custom made stainless exhaust with just 1 box (back box) also had the cat gutted out..leaving its original housing..(engine light is on but remap will turn it off)
taking the cat out makes a nice noise change as u can here the turbo spinning up..
all exhausts will make a different sound..
mine is sensible & muffled,but between 2500-3500rpm its loud..
it sounds like a big engine jap car with the turbo spinning up aswel.
its the 1.4 TURBO gtc.
