This question might be posted elsewhere but on the X350 forum but I've not found it. I want to (just for the heck of it) replace the stock exhaust on my XJ8. Normally aspirated. Mina has a system, but what else is out there? I'm not looking for LOUD...I want Vroom. Louder than stock, but not hot rod LOUD. Any suggestions? Thanks.

I just did mine early this year
I did a set of new 200cell metal substrate cats new 02 sensors all 4 of them
Then used 2.1/4 inch down pipes out of the headers in and out of the cats to the X pipe under the floor replaced the middle muffler and changed the rear mufflers sounds awesome not loud but sounds like a V8 now even my indie commented its the best sounding XJ8 he,s ever heard
I replaced the pipes with 2.1/4 from the headers out to the x pipe
left it stock pipe diameter after the new middle muffler its 2.1/4 in with standard diameter out next time its on the hoist Ill get some pictures

I did all my mods while it was nsw reg then just took it and got a roadworthy on it and registered it in QLD no problems
the guy that owned it before me took it to a shop in Sydney and had the rear mufflers changed it had a real mellow v8 sound it's definitely louder now but also goes much better
Most rwc centres have never done a jaguar and expect a jaguar owner especially a late model owner to be pretty up to date with maintenance not to mention when you get the rwc let him know you are transferring the car and it's not for sale
Can't see it as a problem otherwise i can ask my jag mech he is in Sandgate

I left them on and did my own front down pipes cats and centre muffler
It's louder than when he did the rear mufflers but also goes better not a bad note though my jag specialist said it's the best x350xj8 he's ever heard loves it

I finally got the header tank fixed today and while my mechanic was revving the engine I stood behind it its actually quieter than I thought
I will try and do a recording in the next couple days
Last time I tried to record the sound from my XJR6 on the dyno all I got was distortion [LOL]
