--- Quote from: "Eeyore" ---You can remove the centre box - it does add some decibels to the exhaust, however, it'd still be road legal.

If it were my money, I wouldn't bother with a performance exhaust because the standard one actually does a pretty good job (our Henry for example, races with a standard exhaust but with no centre box). Standard pattern exhausts are also el-cheapo compared performance (or 'blingy') systems.  :wink:

If however you're uprating the output from the engine then you may want to consider a change, but the standard system to perfectly good for 200+ hp.

And remember that noise doesn't equal performance  :wink:

The one to go for is the 3.9EFi or 4.2 system as it's bigger than the earlier ones and TBH my Double S system didn't add much power at all to the 3.9, it's difficult to do anything clever with the V8 exhaust becasue of the firing order.

I fitted the same system to the LSE mostly for reliability, I was forever blowing exhaust manifold gaskets, I think the cats were blocked though as now I get much better MPG and it sounds nicer too.

Like Eyore says though, noise doesn't mean power, in fact that noise probably comes straight out of your tank :!:

For a cheapo system try putting a TDi centre box into a 3.9 EFi system with no back box, we had this on Blue when we first got it.

One other thing to mention, when I get a nice chugging from a V8 it's probably got a problem, a well balanced V8 with good compression on all 8 should give a nice smooth tone, however big the exhaust.
