I have a rattle inside my exhaust.
It sounds like a steel object dancing around inside the pipework or centre silencer.
As the engine is running , exhaust note (cobra race back box) and obviously sound travels meaning its difficult to pinpoint.
Any ideas ? Im hoping Im not going to recieve replys pointing to bits of my cat being blown out ?

Baffles broken up or heat shield

Its more of a solid rattle so Im steering away from heat shield.

Also spent a couple of weeks under her recently buffing and undersealing and I think I would have noticed shabby heatshield fixings.

Cheers for the reply :+1:
