172 Cup catalyst.

[Blarno]

I'm looking at making a decat pipe for my Cup, does anyone have a picture of a cat from a 172 and any important dimensions? I have access to stainless pipe and bending equipment and want to have a crack at making my own. I need a picture to show me where the bend is and what the clamp situation is.

Any help appreciated.

Nice one. I take it it has 2 Lambda sensors then?

Yep precat and postcat, hence a decat tends to put the engine management fault light on as it thinks the cat isn't working.

I can live with that, I suppose. Anyone know any of the dimensions, length etc?

It will be hard to get it right as its got to be just the right shape and size to fit trhough the gap so it doesnt bang on anything.
