Sard T.C.V (Torque Control Valve)- 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.
