Vx exhausts, why so fat? - Big Vern
Vaxhalls come fitted with large rectangular silencer boxes and a decent bore, however I have noticed that the pattern parts are the more usual oval boxes and appear to be a smaller bore. What is the difference price / performance / longevity / etc ?

An interesting question!

My Vectra GSi V6 Estate has an enormous Irmscher exhaust system as standard, with a silencer box even bigger than the 'regular' items, and which only just fits adjacent to the wheel well.

Given that one option I have next year, when the lease expires, is to buy the car, I was thinking of exactly your question only a few weeks ago.

Apart from the argument of 'cosmetic expectation versus geuine performance gain', the car and exhaust design strike the happy compromise of allowing near silent cruising, but with a delicious soundtrack when the throttle is poked, from any revs. :-))
