I've seen the thread I need but can't find it.. so..

Are there any real-world benefits, on a standard Z22SE engine - and it'll be staying pretty standard, to fitting the Vectra C pipe instead?

I know I'd have to drill a hole for the sensor, I'll be fitting a catch tank soon so that pipe won't be an issue. Then there's that little pipe (FPR one?), that'd need another home. Can that create problems?

But I'm more interested in the actual effect of switching from the 'oval' standard pipe to the round one.
