Performance exhaust upgrades

I tried to post a video of the exhaust sound earlier and it wouldn’t let me. I had to use a Google drive type link to make it work. But that could have been the format or something.

And you updating this thread was very timely! Just started driving the XJ-S this season and occasionally have same vibration under a moderately accelerating left hand turn. I did last season too, I have just been procrastinating!
