--- Quote from: "Les Henson" ---The rear 'silencer' is actually a resonator. Some people have said that the noise at higher revs is annoying. Normally people remove the centre silencer and leave the resonator in place, which makes a much better sound.

I normally advocate that on the petrols becuase the front one is normally restrictive and thus hinders the flow of gases. However as both silencers on the tdi are 'straight throughs' there isn't a lot in it performance wise. I did try it with both silencers out but at the std diameter it's just too noisy!
If you increase the diameter to 2½-3" you can get away with it.
On the V8 it does get noisy if you chop out the front box which I did on my old pick-up (no rear cabin meant no resonance) but on Shed I have 2 straight throughs and side exit and it sounds lovely.  :D

I know these are RR pics but same will apply to a 'Quasi'  :oops:  sorry Disco  :D
