Hi All,

I have installed my new TBExhaust on Saturday. There is a loud whistling noise now when I'm driving, whenever there is even a bit of accelerator applied.
I cannot get it to whistle when stationary (no load).
The car drives just great (well, the same as before ).
I've replaced the turbo to exhaust gasket, and there are new gaskets along the exhaust from down pipe to centre pipe, and centre pipe to the diff-back. All bolts are really tight. Clamps on the turbo to y-pipe, and intercooler to throttle body are tight.
I thought it might be a boost leak, but not sure how to check it. How can I do that?
Could be that the y-pipe is cracked? It was a real pain putting the TMIC back on!!!
If I don't manage to find out what the cause is, I'll have to take it to the workshop before Collie.

If you have an air leak and are still using the afm it would run like sh*t! if its an exhaust leak you should be able to pin point it at idle!

When i went from a Stock Dump to After Market I could hear the turbo alot more. Maybe thats what your hearing?
Have you got a boost gauge? If boost is holding and its driving smooth I reackon its just the noise from your turbo

Pretty keen to hear how you go with this.. mine does the same, but only under full load 4th-6th. Only suggestion I've seen so far is gasket related, but you've got that covered!

What style dump have you put on?

Thanks for your responses guys.
Dump is bellmouth style. Before I fit the exhaust, I could hear the usual induction noise, but this is much higher pitch than that.
The car is running absolutely fine, so I assume then that would eliminate a boost leak.
I don't have a boost gauge so can't check the boost on that.
Might have to drive it to a workshop for them to listen to it and see if it's abnormal. I haven't heard any other cars sounding like this though.
