Tuning XJS Exhaust Sound

I'm still anxiously awaiting that YouTube link, and, I think someone else requested a parts list

Exhaust Mods, liking it
I too wanted a little performance and sound from my '89 XJS, so after reading on this forum last year, I first changed out my stock air cleaner boxes and replaced them with K&N system, then gutted both sets of cats and replaced the mid muffler with straight pipe and added 3"X5" SS exhaust tips beneath the bumper.
I really like the difference, and definitely feel more low-end pulling power under acceleration and love the high-pitch 'singing' when launching. I often use 2nd gear to aid in slowing down, and the burbling sound catches attention too.
She's a great old girl, I drive it like it should, having put 44,000 km on it since buying it almost 4 years ago.

About to finish my home made stainless steel exhaust system with magnaflow resonated x pipe. What do you guys think?

Details needed!
Cat delete? Can you take a underside pic or draw diagram? I need that raspy v12 sound at idle.

What system do you run?
From my experience the cats dont make that much difference in the note. I gutted them out long time ago while having the stock exhaust with mid silencers removed - very small difference in the note.
I wanted to achieve more V12ish note, which in case of an XJ/XJS is in my opinion only possible by merging the two sides of the engine at some point (X or H).
I also picked rather small diameter pipes all around hoping to avoid too deep more like V8 muscle car sound, cos I think that just doesnt sound appropriate for the jag.
I am not sure if my amateur ideas did the trick, but I am very happy with the result.

Gutted cats, same size pipes as you, 2 glasspack high flow mufflers to side exits ahead of radius arms. Stupid of me to toss the stock resonators they would of been better than mufflers.
I KNEW I should of done the X pipe...I have one in a box here, at 5000rpm in 1st gear its a menacing rasp, and the idle/rolling idle grows like an actual Jaguar cat but that mid range where we do normal driving is just lawn mower-ish.
Mine doesn't snap and rasp while reving like yours. I'd start calling them professional ideas you've done better then me lol.

My first XJS had a hard shift from 3rd to 4th gear, so I always drove in 3 while on surface streets. I had all of the mufflers out, and used 4 glasspacks for some growl. The combo of driving at higher RPMs in 3 with the glasspacks made it a great drive and interestingly had an exotic tone to it.
