172 Cup CAT Removal

[Spud1985]

Trying to search the forum on Tapatalk by can't find one relevant post . . . . So . . . . How do I remove the CAT from the manifold? Is it simply undoing the spring bolts and it will slide out, or are there other obstacles in the way?

Undo the bolts at each end of it. :S

172s are a complete pain to do as the ones engine end are really awkward to get to.

Good luck.....!!

P.S.: it's not an abbreviation.. It's a catalytic convertor.

Already took the rest of the exhaust of just need to undo the cat from the manifold. I'll keep persevering with the spring bolts then.

p.s. i've always wrote cat in capitals as for some reason when it's not I associate it to the furry kind. But for this post I have changed my ways

You need a mate to hold a spanner on the bolts from inside the engine bay - then undo from under. Otherwise they just spin
And it's a PIG to get to the bolts in the engine bay. In all honesty I'd take the top inlet manifold off as then you've got loads of space

Took me and my exhaust builder an hour on a ramp! bit of a pain, so glad i had my exhaust modified like a 182 so its a 20 min job to swap round

It's a track only car so once the cat is removed and the decat fitted it won't be changed again.
