Stainless steel exhaust
After getting our Bongo serviced have been told we need new exhaust, back and middle section. We are getting the whole lot replaced with a stainless steel one by MIJ Performance in Walsall.
We need to decide whether to go for quiet, medium or loud. Definitely not going for loud but can't decide whether to go for quiet or medium.
Anyone else got a medium & if so what is it like?!

Noisy or quiet exhaust
Seeker says 'noisey equals more power', is this a fact or just as in a wonder boy racers head. 

not necessarily true.
Noisy tends to mean more gas flow, and therefore potentially more power at HIGH rpm..
at low rpm engines like a bit of exhaust back pressure, and so a big fat boy racer tin can will actaully reduce low rpm torque and engine flexibility.
An expensive exhaust will be tuned to take account of the pulse timing from each cylinder to ensure the minimum restriction to flow, but this has to be done as a whole system not just the back bit.
Diesels are not limited by the flow of gas out of the system (they are turboed) they are limited by the speed of combustion propagation in the cyclinder and so there will be limited to no beneifts of a freerer flowing exhaust on a diesel, but it might sound more rorty... or boomy depending on your preferences...
So no noiser is not more powerful...

andyfb78....very true which is why I always laugh when I see these boy racer with exhaust pipes 4" wide and you know about a foot under the car it connects to a 1" pipe..... ...saying that though there aint a better way to bug**r up a lovely motor than to stick on some hideously over restrictive pipe.....
