This car is due MOT soon. Last two tests it has struggled to pass emissions test. Left hand catalyst section rattles all the while, cat matrix probably broken. I have bought a cheap cat secttion in case I need it. Shall I also need a new gasket, if so is above the one?

Nick W:
That is extremely expensive when any local factor will have the same part for pennies. And you'll be able to check it's the correct size before you buy the thing.

Doctor Gollum:
Not to mention completely the wrong part :-X

the cast manifolds have a counterbore for that type of seal. Which is an ordinary part and available anywhere once the size has been established.

Doctor Gollum:
I stand corrected then, the 3.2 uses a flange gasket that bolts through  ;)
