2005 Mazda MX-5 buzzing on over run

Car: Mazda MX-5
Year: 2005
Variant: s-vt sport
Categories: Running Rough, Starting & Power Loss
when the car is warm there is a buzz or vibration when i take foot off accelerator. It comes from below over my right shoulder. Gear box was recently raised by an inch as a clutch judder fix, that and new clutch plate sorted it. is there something that I can look at on the exhaust side of things?

I've had this on another car where the plates in the Catalytic converter were starting to break up. Best to get the car on a ramp and give the cat a firm but gentle thump - if you hear a rattle from the cat that is probably the cause.

Hope it doesn't cost you an arm and a leg. Nice cars these. Happy zoom zooming.

if the downpipe has a flexi joint then make sure this is`nt knackered causing a vibration
