My 760T had a lovely Jetex aftermarket exhaust, nice throaty burble, and seemed to be quicker for having it on. Alas I chose the mild steel not the stainless because the stainless came only in gigantic single tailpipe - totally ghetto looking - and I wanted twin outlets that looked like the Bentley Mulsanne turbo.
Well, that was 4 years back and the back box just fell off days before my MoT test was due,
I rang up Jetex and the nearest back box was in Sweden, would cost ?104 + VAT (at 20%) and would not arrive until the middle of next week.
But the overaxle pipe was still good and there was a bit left pointing straight back - so off to Maidstone exhausts for a bit of pipe that would sleeve nicely over the Jetex pipe that was left. Fitted lovely, looked fine (just a little bit bigger than the Volvo 2.5 inch outlet).
Nice sound, a bit less burbly than the Jetex silencer and sounding actually quieter than with the Jetex rear silencer box!
Now here comes teh shock. Because I still have a standard CAT and the Jetex centre box (huge) I really didn't expect deleting the back box and substituting a bit of large-bore pipe to make any difference (and if anything the reduced backpressure to give better grunt) - but she feels quite a bit slower, boost is slower coming, and all the change points on the autobox (ZF22) seem lower.
Who'd have thought it? It looks as if I need to order the Jetex box after all.
