cat for mot
so i have a hawk sti with a full 3" decat system.
3" downpipe of unknown brand
3" center section by scoobyworld (afterburner) non-resonated
3" afterburner vortex backbox
my usual guy i use for mot's cant do them anymore so i think its easier if i get him to fit a cat just for the mot, exactly which one would i need?
cheers

As Smurf said, it wants to be as close to the turbo as possible. Cat in centre pipe won't work. I have a friend who has a Litchfield Forester STI and it has a sports cat in the centre pipe and fails MOT emissions every year without fail.
Cobra make a full 3" downpipe with sports cat.

Is it to be fitted all the time or just for MOT`s ?
Reason i ask is it take ALOT of heat to get my sportscat close to passing a CAT emmissions test, i mean, up and down the bypass twice at 70 , ingo MOT station and do emmssions test straight away and then it still needs idle revving to get back to correct heat.
if its just for mot id stick a normal cat in it to be safe

To be fair i need to give mine a blast to pass, but always does, thought thats because mine is just a summer car. Thats 200cell, you can get 100 cell that should pass alot easier. Also mine is heat wrapped. Be worth wrapping your exhaust manifold aswell if you go down this route.

Think you'll find that's the other way around.
200 cel is more MOT compliant and easier to pass than 100 cel which is less restrictive and lets more harmful particles through.
I had a 200 cel cobra on my car and passed MOT fine every year without having do drive it like I stole it beforehand.
