Anyone seen these? SARD TCV (Torque Control Valve).

How it works:


its a high flow cat, when at 60% or so it acts like a test pipe? Anyone have one of these? I want to get one for my civic

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.
Installs in place of main catalizer, rebuildable unit.
Fitment for Nissan vehicles only.
Available for Nissan 300ZX (Z32), Nissan 240SX (S13, S14, S15), Nissan Skyline (R32, R33, R34)
For off-road use.
Just say no!

To begin with, it's not a high-flow cat, it's just a fancy test pipe. I doubt very much that there would be any real gains over a traditional test pipe or even a good high-flow cat, but if someone were to present some actual dyno charts, I'd be interested in seeing them.
