Hi There, New to Forum so Hey

Car went into MOT today, now I knew it had a full custom exhaust system from 'Longlife' Flex/Knuckle through to back-box. No Cat present and due to New Laws this year that means it fails MOT.

The thing I didn't know is the previous owner also put on a custom manifold.

Now I'm not the most clued up on cars but have basic knowledge. Garage is saying they need to fit a CAT in order to pass MOT. OK fine.

I just need to know best way, fit CAT to current system? Will it fit? Or Do I have to Change manifold back?

Just need to know the cheapest way really, don't care if I have to lose the manifold, might even sell it? Would rather keep rest of system thou?

Any help would be really appreciated

Thanks

Ben
