Modified Exhaust Systems (An Archive of Links to Previous Discussions)
Modifying the XJS exhaust seems to be a popular topic, so it makes sense to consolidate previous & future discussions into one thread, which can be easily found in the archives, and also posted into replies whenever a new member asks how to do it, if there are any pre-manufactured systems, headers, etc.
These are just a few discussions I can remember, but, by no means represents the entirety of discussions on the subject. I would like to see other members add comments, links to other archived discussions, vendor links, and, new (or old) ideas for their own custom exhaust systems.
Without further ado, here are a few links to get the ball rolling:

https://www.jaguarforums.com/forum/x...xhaust-120792/
Sorry, I didn't post the finished product, and, I think I deleted the videos from Youtube, but, there is good discussion here about modifying the restrictive US market down pipes.

The Black Pearl may not sound quite like the Targa XJS, but, Marko still has it sounding darn fine. From what I've seen of the Targa XJS, all 12 cylinders exit through a large collector in front of the rear wheel, on the driver's side of the car (right side).
I imagine much the same sound can be achieved on a dual exhaust setup by using a crossover pipe. That is assuming you also have reasonably large exhaust, that you have a free flowing intake system (an exhaust system can only expel as much air as the engine can suck in), and, that you have lightened your rotating mass as much as possible to allow for faster revs & faster deceleration, as the Targa XJS obviously has. Much of that crisp sound you hear is because the engine is able to rev so quickly & freely.

something like my Exhaust ALL 12 cylinders out of right side ,done 22years ago, still sounds awesome, because your ears hear all the sound from one place!!

Jagzilla said it correct!. light weight rotating components, from front damper to converter.
listen to some of those exhausts , count how long,in seconds, it takes the engine to come and back to idle, from guessing 3000/4000 rpm,going up and back down to idle!
a quick rate would be around 1/ or 1 1/2 seconds, up and down,together!

that is still two outlet pipes!!
your ears hear one side then the other side, back and forth/back and forth,etc.
brain gets scrambled, not happy with the sound!
