The exhaust bracket is very highly visible. Bolted to the gearbox close to the sump of the engine. Not much room there for the exhaust. It is not an easy bracket to make yourself because of the angles required. Without it the exhaust is going to move around.

Please have a look and confirm that bracket is there and keeping the exhaust clear of the engine and gearbox!

I had this with mine, honestly I had everything checked about 3 times. Clunked over speed bumps and every time I turned right. A wonderful friend and mechanic knew exactly what to look for and I can't for the life of me remember exactly what it was but it was a bolt that had come loose somewhere near the steering arm.... as simple as that x
