Ashley exhausts

Eh up everybody, I was thinking of getting myself an Ashley exhaust system from manifold back, so?

Has anybody fitted one how loud are they?
Are they easy to fit?
Are they any good?
What size do I need 2 inch or 2 1/4 inch(GTI Campaign) I've not got any calipers and everybody quotes these sizes :y:

the 2 1/4" is loud. quality is not great but they are cheap. don't expect an easy fit and you'll be fine
