Frequently Asked Questions

InLineMount – Some vehicle configurations do not allow for clearance around the turbocharger, for installation of a DirectMount exhaust brake, these applications require an InLineMount. Inline exhaust brakes require a minimum 7" of straight exhaust pipe which is then cut out and exhaust flange adapters are installed in its place. Ensure the exhaust brake is mounted as close to the turbocharger as possible and away from road spray. NOTE: Clamped joints that exist between the brake and the engine must be welded to ensure that the joints cannot separate or leak under pressure. No flex pipe is allowed between the exhaust brake and the turbocharger.

DirectMount –This application is preferred because of the reduced number of connections between the exhaust brake and the turbocharger. The mating surfaces are both machined cast iron which eliminates any chance of exhaust leaks. For vehicles with straight back systems shortening of the header pipe is required to maintain an adequate amount of flex pipe. Vehicles with a 90° header pipe use a cast elbow to interface with the stock header pipe. Pacbrake offers replacement header pipes for some truck models.

This is a traditional style exhaust brake tuned for maximum allowable backpressure at the maximum engine rated RPM by the drilling of a carefully selected hole size in the butterfly valve.

This application is the preferred option for vehicles with a tight 90° bent header pipe post turbocharger. The cast adapter is constructed from cast iron with machined mating surfaces on both ends, eliminating any chance of exhaust leaks.

No, you cannot. This spring is specifically calibrated and adjusted and made tamperproof on the assembly line. This is done to ensure each application is matched to the maximum engine backpressure and will not cause any damage. Tampering with the springs will void the warranty and potentially cause severe engine damage.

The exhaust brake requires very little maintenance. If it is switched off the brake will go through an "exercise cycle" which activates the brake 3x at startup. This is to ensure it does not stick or seize up with inactive use. Also, it is recommended to apply a few drops of Pacbrake Super Lube to all pivot points every 3-6 months.

Every Pacbrake exhaust brake has a 1/8" NPT port tapped into the side of the exhaust brake housing. It has a port plug threaded into it from the factory. Remove the plug and install a back pressure gauge to this port. Go for a test drive and observe the backpressure readings.

Yes. This is a normal operation if the engine is not warm. This allows the engine to warm up sooner by increasing engine load at idle. This feature can be turned off by cycling the toggle switch 8 times.

Yes! This is a bonus feature of an exhaust brake. It creates a restriction at idle that puts a slight load on the engine, causing the engine to warm up faster.
