Sleeving exhaust 4.6 V8 Range Rover
Discussion
Afternoon All,
I've recently bought a P38 Range Rover 4.6l V8 and looking to release some of the restrained soul from the V8.
I've got the centre box at a fabricators who's cut it open to reveal and rather interesting maze!
My initial idea was just to sleeve the insides with a straight through tube- but concerned about the complexity inside. Is this just for reducing noise? Or does it tune the exhaust and engine performance? or both?
I realise the range rover is tuned for torque rather than power and probably needs some back pressure. But there is also the two back boxes which don't look 'straight through' either.
So... any ideas what the best option would be to release some more noise, but keep performance? I am initially thinking of welding a direct pipe to the second chamber (red arrow) and maybe wrapping the perforating tube to stop the baffle working. If it's too loud I could open it up and take off the wrapped section.
Many thanks for any help!

You'll probably find that removing the back box and replaciing it with some pipe will provide the result that you are looking for.
I only run a single centre box on my hybrid and it's got just enough V8 sound and is very quiet when cruising (or perhaps all of the wind noise drowns out the sound...)
It also gives you the opportunity to make the exhaust exits look nicer.

Thanks for response. The problem is a have twin tailpipes so would mean more money to sort those. Plus I have my centre box cut in two at the moment... so keen to do something with it.
Much prefer an understated standard look as well- just TVR noise!
Just spoke to fabricator and decided to do a straight pipe welded in. Should be interesting!

Some of the best noise comes from increasing the induction. This is done with a sports air filter (eg K&N oiled filter)/ induction kit.
If you're not sure, and before you spend any money, try removing the air filter (only temporarily as it's not good to run like this for long) and see what I mean.
This will only cause noise when you open the throttle, so it goes quiet once cruising. I was presently surprised by the addition of an induction kit on my wifes old VR6.
