I had one of THESE on my car for five years. Fit perfectly, with no issues.


They have 3.2 ones as well, but they're £200. That would be worth the £10 for a lambda boss and a few seconds welding to do away with the pre-cat to me.

i'm sure I've seen clamp on lambda bosses that require no welding, just a hole
can't remember where though  :(
but don't the 2.5 cats have different clamps to the manifold  :-\

You have to trim the top of the downpipe slightly where it enters the manifold.


Flap disc in your best precision angle-grinder.

which is about what you get if you draw round with a sharpie resting on the flange.


But that's probably too simple to be an OOF recommendation......

I think it is approved as long as it's a genuine Sharpie ;D
