~(11 lbs. 16X10X6)~ EXHAUST BRAKE-PRXB ISBe (BAE)

Pacbrake’s flagship PRXB exhaust brake offers the highest braking power to lowest price ratio in the supplemental brake industry, providing unmatched performance, safety, and durability. It replaces the stock elbow and creates restriction at idle for faster engine warm-up. This direct-mount application reduces connections and eliminates exhaust leaks with machined cast iron mating surfaces. The unit is tuned for maximum allowable backpressure at maximum engine rated RPM. It also includes an "exercise cycle" that activates the brake 3 times at startup to prevent sticking/seizing. Requires minimal maintenance with recommended application of Pacbrake Super Lube to pivot points every 3-6 months. The springs are calibrated, adjusted, and tamperproof to ensure maximum engine backpressure without damage; tampering voids warranty.
