Just wondering if anyone has got one, used one, or had any experience with em at all?

The idea of it sounds great, but i am not sure if it will give the gains they say it will or even if the gains would be noticeable haha

A bit of info...

1. T.C.V. is developed to increase low-range torque and improve torque response at low to mid speeds for race applications with a sports-type exhaust system or a catalyzer replacement pipe.
2. T.C.V. offers a great flow, similar to that of a straight through muffler, while the valve is open.
3. Noise reducing function of the valve works during idling or running in the low range.
4. This system is a bolt-on application to exchange with your catalyzer.
5. System and valve unit are made of durable and heat-resistant stainless steel.

'This replaces the catalytic converter, and a better alternative than using a 'test pipe'. Torque Control Valve operates on exhaust backpressure to provide low end torque at lower rpms, and high end power and mid through upper rpms.

On higher horsepower vehicles, lower end horsepower and torque is lost in favor of peak horsepower with larger diameter exhaust systems.

The Torque Control Valve (T.C.V.) operates on exhaust pressure to provide a broader range of useable power, for better low-mid range power and torque, without sacrificing peak hp. The T.C.V. can also assist with quicker spool time on turbocharged vehicles.

During idle and low rpms, backpressure keeps the spring loaded aero duct engaged and restricted, for reduced db and optimal exhaust gas velocities. During mid-range and higher rpms, exhaust gas pressure will push the exhaust fully open for the best power and flow.'

For a turbo'd motor, restricting the exhaust after the turbo is the worst idea I can think of (in terms of performance)

Wing is right, not good for a turbocharged engine.
Turbocharger spins because of difference in pressure between Engine side and Exhaust side.
If you increase pressure on exhaust side the difference in pressure is reduced so turbo gets less energy from the exhaust gases.
I guess you might be able to use it to stop the turbo overspeeding...
