mk2 g60 manifold and downpipe

[VwJunkie]

Hey guys,

I bought a mk2 g60 manifold and downpipe, now i think the downpipe is 55mm and the aussie cat is 50mm right? What kat would fit this downpipe or should i just go and decat it?

Cheers, Stefan

no cat is illegal for post '88 cars, but why not go to a 2.5" cat... that'll weld up easily on to 55mm pipe.

(you cant really get exhaust tube/parts in metric sizes in australia)
