I'm still trying to figure out what's out there and available aftermarket for these old gems, but if anyone's wading into it like me, maybe i can prevent a mistake.

I'm in the US and saw the Moss motorsports bits for the exhaust and they were pretty inexpensive. I was also aware of the 'stage 1' droning for the adamesh (and others that remove the rear cans maybe). So I thought I'd try the moss over axle pipes and the front center box replacement (not really an x pipe - just a smaller resonator).

When I got the Moss one, it was OK - not something you'd want on a show car - but the problem was it wasn't bolt on. You'd have to cut one leg of your stock center box assembly (one side is a slip fit, the other a bolt flange to the cat - the Moss has both as a slip fit). Also the over axle pipes were not going to engage with their own center box pipes without a spreader or cutting.

So I sent them back and they were good with customer service and always answered the phones. A little miffed they didn't refund shipping since it was not bolt on and was not going to fit.

Then I got the adamesh from the UK and it is a much finer "peice of kit" (don't you all say that?). Much nicer bends, much nicer pipes and material and two piece over axles so slightly easier to install ( still a bit of a hassle - jaguars fault there).

Anyway just one bit of feedback. Moss seems like a reasonable company and I wouldn't rule them out for future things, but I'd avoid the exhaust unless you're just in repair mode rather than upgrade mode.
