Twenty years is a pretty long time for mufflers to remain without issues. The Bimmer muffler lasted 26 years.
I love the quiet of the Duchess as she navigates the highways. That smooth effortless glide with no road noise
is something that satisfies my expectations fully.

I love these cars. But I've only heard a few of these cars with a nice sounding exhaust. A lot of that has to do with not many people modding these cars, imo. Stock is way too quiet for me. Luckily I have S/C whine. That said, I'm thinking no kittens and x pipe with mufflers a tad louder than stock should sound nicely. @XJR-99 has the best sounding x308 xjr imo.

Spent a little time in the car today and the exhaust is growing on me a bit. Will still probably look for a spare exhaust system so I can add an x-pipe and keep my stock exhaust in case I want to go back. Is the XJR exhaust different from the XJ8? Wondering if I need to find an XJR specific stock system. I know the tips are different from the XJR/XJ8 just not sure about the rest of the system.

Not long ago I looked at a pair of XJ8 mufflers without the brushed tips on and discovered the pipe diameter was smaller than that of an XJR. I don’t have the exact number but I seem to this it was about 1/8” to a 1/4” difference. I’m talking about the pipe coming out of the muffler, I’m not sure about the inlet pipe diameter difference.

Mr nilanium ......
I wish I'd read the earlier posts in more detail and seen that you were asking about deleting the rear mufflers, I'd have chimed in with the same results that others have said. You get basically the same effect to test out by just removing the rear muffler sections and going for a drive around with the mid-muffler pipes dumping into the wheel wells, a tiny bit more grunt but a REALLY bad resonance at 2k rpm. Obviously don't do this for extended periods since it'll dump onto your tires and heat em up, also exhaust fumes probably aren't great for rubber longevity. I think I've heard elsewhere that X-pipe in the shared muffler, and possibly deleting the mid mufflers if you really want noise, but keeping the rear mufflers in place is a good move.
I've been considering trying out supersprint X-pipe 131012, I have a spare shared muffler section where the muffler is bad. It seems like you can just cut out the muffler and slip that X-pipe in place, but I haven't been able to get a clear answer from Supersprint on if it requires additional parts or mods, the X-pipe looks a bit shorter than the OEM muffler... That and there's other places I need to put money towards on the XJR, such as buying another set of tires which hopefully don't cause highway vibration, really hoping that it's just bum tires there and not something weird frame related.

We love to have our cars "sound" like our cars. It's not unusual to try different things that personalize our ride.
I can tell you that the Jaguar engineers wrestled with the issue for a while before coming to agreement.

Will do. It's growing on me and I've been driving the car more, but still only occasionally. Should be able to get my new tires mounted next week and then I can put some serious mileage on her. That will be the real test. Still haven't had it out on the highway for an extended period with the new exhaust so we'll see.

Indecisive? Me? Not sure whether I am or not
but leaving them on for now.

I've been driving it every day and I don't know whether it's because I've been subconsciously driving around the boom but they are definitely growing on me too and the resonance feels less intrusive.

Update
Yea, same here Mark. Have put about 100 miles on the car (still no highway trips) and I'm definitely liking it more that I was initially. Definitely leaving them on for now, the car definitely has more presence now making a little bit of rumble. Funny that we're both slowly coming to the same conclusion.
I just had to put a new down pipe/cat on my car and decided to put the stock mufflers back on. The drone at 2K revs finally got to me. I love the burble but I want to get back to Jag serenity.

Hi @87LC2 , how are you getting on without the mufflers?

On the other hand, I've since purchased a 2006 XJ8 for a daily driver and that car actually has great engine noise from the factory. Not much exhaust noise, but you can tell there's a V8 under the hood when accelerating. No way am I touching anything on that exhaust system, its perfect as-is. It's too bad the x308s didnt have just a bit more sound from the factory, if so I never would have touched it.

Now, what about an X-Pipe?

Absolutely get an X pipe in place of the large single front muffler and straight pipe the two center mufflers in front of the differential. Leave the factory rearmost mufflers alone. No drone, sounds great and not obnoxious.
