Ya I had High flow Cats to Xpipe and no mufflers out back and sounded glorious but it really didn’t suit the Jag. The backfire was like an M100 going off. If I had an ftype, loud would be better but this car is a luxury car mostly and it cruises well. This is where the valvetronic mufflers come handy wether your cruising long distances or racing the car, you can switch the sound on the fly.

It's about as loud as the stock 6.3 Mercedes AMG engines from 10 years ago

Sorry one last question. Do you have any drone at all?

I think there is a slight drone between 1,200 - 1,500 rpm. The car doesn't really operate much in that range to be annoying though.

I'm not even sure I'd call it a drone (definitely not like my old 5.0 mustang). The sound is just a little bassier.
