Petrol engine sounding like a diesel?

Can you make a recording of the sound? Will it happen if stationary and you hold the revs?
I will try to record it, although it is one of those sounds that only I can hear, I can only hear it on load and no sound in sports mode , and it goes when not in sports mode when you reach the rev's where the sports flap opens, which is why I was going down the exhaust leak route, just wondered it they were prone to cracking, or joint leaks?
Common issue, it will 100% be the flex joints alongside the engine on primary cat pipes.
Literally getting one of mine cut off tomorrow at Longlife exhausts, going to be £250-£300 he reakons. He plans to make a new flex pipe which slides/clamps on, he hopes to weld on but worst case it will clamp on.
I think its just the passenger side for me at the mo. It's going to be a pain in the arse as the access is tight and to remove the primary cat with its rusted studs is a nightmare job, access to 1, maybe 2 of the studs looks impossible but the plan is to attempt the job with the pipe in place.
The drivers side is seriously tight, that's the one you don't want to be broken!
In the US, they make replacement flex pipes but sadly not for the 4.8.

Now thats a result! I had a similar result last week on my other car. Nasty knock from underneath. Fearing expensive suspension issues and turned out exhaust mount had gone. £5 fix.
