Default What is the standard size/bore of the exhaust on an Impreza?

Hi

What is the standard size/bore of the standard exhaust on an Impreza, both the UK model and import version (not sure if they are the same or not) - on the classic shape impreza? Is it 2.25" or 2.5"?

Thanks

Matt

Is that a 2000 year classic shape? Do you know what the import (wrx) classic shape Impreza exhaust diameter is?

Yes mate, classic shape. Just double checked with the tape measure on the standard centre section that I kept, definately 2.25".

Don't know about the import version though

Just looked at my mates exhaust and its 2.25" bore on a v1 Impreza import WRX, is that correct size for a standard system?

My old classic had a 2.5" standard bore, i've never seen a 2.25" on a turbo classic before?
