Thanks Marque (also for your reoply re. tyres). I'd heard about Mini's running better with a cat so will take your advice and avoid the decat route. I'd be happy to sacrifice my old manifold, could a decent exhaust place manufacture a tomcat i.e. is it just a chop and weld job, or is it more involved than that?
A good exhaust fab place will be able to modify it but just check they can first.
but you will have to fit the manifold first and make it to fit ie correct lengths and flange angle so it's a perfect fit as mini to mini they very a little.
you will need a flange for the cat to manifold joint but it's an easy job a good exhaust place should have these.
