Not sure about cats Dave - we don't have to have them here in the UK until a car is as new as a 1993 model! Any older than that and we whip them off in a flash, replaced with straight pipe :) Are you taking about what I would call a downpipe? The pipe from the turbo that drops down under the car to meet the catalytic converter? IIRC, the 99T exhaust manifold meets the charge pressure regulator (which the turbo exhaust side also meets) and the exhaust drops off underneath. I'd be very surprised if a downpipe off a 900 would fit - the turbos were different (no charge pressure regulator, sadly) and the downpipe came out sideways and then dropped down. It is possible that if you took the exhaust manifold, turbo and downpipe off a H type, it'd all fit together. You'd lose that nice walrus sneezing sound though :) Paul 1989 900 Turbo S
