JTS 5000rpm engine noise!

When my engine reaches 5000rpm in any gear there is a loud exhaust resonating sound from the engine. I discovered the baffle had gone in my rear box but having this replaced has not cured the problem.

Engine is smooth at idle and no excessive noise at low speeds..

Any ideas?

Could be a heat shield loose?

Re: JTS 5000rpm engine noise!

I think its more than a heat shield its a louder deeper sound than i think that would be.

I noticed today that the air intake tube that feeds the resonator chamber was loose and all of the air would not have been entering the chamber.

I will be taking it for a spin later to see if that was the cause of the noise.

If its still there I might end up taking it to ALFA to sort it as I am running out of ideas of wht it could be.
