Range Rover Blues:

--- Quote from: "DEANO3528" ---
--- 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

Which would explain why Blue had the centre box from a TDi on it, and nowt else, nice :twisted:

My V8 has been de cated, and just has an american center box only (i think its a turbo muffler) no back box and side exit.
Done by pipecraft in basildon in Essex.
Love the sound, very pleased with there work.

I had a look on the screen at work today, i just need to get some pipe and get happy with the hacksaw. Look easy enough and there some suuitable tax disc holders down the road that tidy the end up nicely.

Have you seen that Cheviot are doing cat free front pipes for the 300tdi for £20 ?!! No flexi pipe but a bargain price !
