Loose Vibration Noise ... Help Please

[christurbo]

When I took the car out to test my new wheel - when warmed up there is a vibrating / loose vibration sound when I accelerate and hit around 5.5-6k+ rpm... then if I drop down the box at high rpm [heel and toe] decelerating it happens too.

It doesnt happen when accelerating/decelerating upto about 4krpm. Or driving normally.

I think it might be the exhaust or the heat-shield vibrating on something as it is coming from directly below me/slightly behind....

It has a std exhaust - however...

I noticed when looking under the car that the previous owner had changed the exhaust as the exhaust should be just one piece from backbox to near the cat, mine is in two parts which has a join by the rear beam.

Anyone had any experience, or can offer some thoughts/tips?

Im not too worried if its the exhaust as I'm getting the Yozza Rag Exhaust fitted soonish.

Thanks

Chris

Sounds like a loose heat shield to me.
