i have full system too

aslong as the system is corsa-specific then the cat/decat will be a straight swap

i thought the pipe diameters were differant on an aftermarket system (eg; magnex) plus if you get the pipe from the manifold back when you cut a section of pipe out to put your cat back on after the MOT you wouldnt be able to get the straight bit back on cos you can't sleeve it.

if you see wot im saying

I just say my engine is based on a nova SR block from a '90.
But guess you couldn't make that stick so easy.

As if anyone on here is really concerned with details such as what's legal and what will get you locked up with your new roommate "big Shirley".

Why not fit a decat pipe? They REALLY do add less than 1bhp! Can't be bad.
