How to pass an mot test with a decat?

Calling for help from the forum, I am looking to decat the clio but I dunno how I am going to get it through the MOT, any suggestions???

Regards

Chris
 
the mot rules also make it a fail if they notice the cat is missing...and the second manifold cat is no guarantee it will pass an emissions test given that
the two cats combined are there to reduce all pollutants - hc co nox

best find a slack or blind tester
 
And void insurance if in crash, not 100% sure that is true would like to know for sure as I would like upgrade exhaust
 
It would all depend on what you have declared on the insurance. With the likes of Greenlight and having all modifications declared you're insurance will be fine.
