Mk2 de-cat?

[eltax91]

Hi guys

I know the cars need cats for the mot, but now I'm supercharged I failed the emissions this time around. My cat is knackered.

So, my local tuner follow found a 'sympathetic' tester when it comes to the emissions. He's suggested that I should de cat the car and just use said tester come mot time. Let the car breathe that bit better into the bargain.

So, having Googled it, it doesn't seem that easy to find a de cat pipe? Where do I find one? And is it an easy home fit job? I'm running a mk2 1.8
