The Pacbrake C44075 is a direct-mount, 4-inch exhaust brake kit with a max-flow design, providing significant braking power and enhanced safety. It includes a controller (if required) and an AMP Onboard Air Kit. This system improves engine warm-up time at idle and features a 1/8" NPT port for a back pressure gauge. It requires minimal maintenance with an "exercise cycle" at startup and has a calibrated, tamper-proof spring to ensure maximum engine backpressure without damage. The DirectMount application is for vehicles with a tight 90° bent header pipe post-turbocharger, utilizing machined cast iron mating surfaces to eliminate exhaust leaks.
