FAQ

What is Variable Orifice Technology?

It’s a design that adjusts the exhaust restriction dynamically across RPM, providing smoother and stronger retarding performance over a wider range than fixed orifice designs.

Does this exhaust brake require modifications?

No major modifications are needed. It mounts directly where the turbo outlet elbow connects and uses the included air-actuated butterfly assembly.

Will this improve towing safety?

Yes — by creating controlled exhaust backpressure, this brake helps slow your truck without excessive wheel brake use, reducing fade and improving downhill control.
