TBE install, now I have a loud chirping sound
Just got a TurboXS stealthback/Prodrive axleback. The exhaust note is nice and low, but when I get on the throttle, I hear a pronounced chirping sound, even before I get to 3K RPMS and the turbo starts really going. I can even hear it at idle, albeit not that loud.
Any ideas?

Turbo spool or wastegate flutter will both be much louder with a tbe. If you don't think its normal then you probably have an exhaust leak. I would reccomend listening to another car that has a tbe and compare the sounds.

I heard a couple sharp rapping noises before I first noticed the noise. I also thought that it wasn't pulling as hard, but I chalked it up to my imagination. Now I've also noticed a wooshing noise (like wind) when I get over 3000 RPMs.
Sounds like a visit to an exhaust shop in my future.

I have the TXS tbe, and if you are describing the 'tea kettle whistle' then its normal. The huge downpipe causes turbulence resulting in the whistle.
If its a metallic screech or chirp, it may not be installed/fitting correctly. Im in the east bay if you want to hear mine.

I don't get a chirp with my APS downpipe/turboback, but I definitely get a WHOOSH under the passenger-side floorboards when I gun it, right as the turbo spools up. 3" exhaust is no joke! I've ridden in a friend's car which has a vf34 upgrade running 22psi of boost, and when he hits 3500 RPM the sound is like a vacuum cleaner (his APS CAI whooshing from the front, APS downpipe whooshing from the back of the engine!).
