Dynamometer Hose (Dyno)

Dynamometer (dyno) hoses are crushproof and can withstand vehicle exhaust temperatures of up to 700°F, when used with a fan-assisted system. Dyno exhaust hoses are made of a rubber blend that is formulated to withstand the high temperature of a dynamometer and work alongside dynamometer engine testing to prevent emissions from reaching toxic levels.

Dyno hoses have a 4-inch inner dimension, are 11' long, and survive in applications where other garage exhaust hoses cannot. Dynamometer hoses are compatible with F475DYNO or F350DYNO tailpipe adapters that are made from the same material and feature a hole for sensors or probes to be inserted during dyno testing.

WARNING: Vehicle Exhaust is extremely dangerous and potentially deadly. We always recommend that any system be properly engineered to meet the specifications of your application. If you are using our Crushproof system, we recommend that you use it with a fan and as an intermittent repair solution only, not to be run for long periods of time. This hose is to be used only with naturally aspirated 4 cycle engines running at an idle and under no load. We recommend keeping any run of hose as short as possible preferably 11' or under and sized to include ambient air to cool the exhaust temperatures. This hose is designed to handle frequent temperatures up to 400° and intermittent temperatures to 600°. When using Crushproof hose for the first time, watch closely to verify that the exhaust is exiting the building as designed. IF YOU SEE ANY EXHAUST COMING BACK INTO THE SPACE, THE HOSE IS NOT BEING USED PROPERLY. TURN THE VEHICLE OFF IMMEDIATELY AND CALL OUR EXPERTS.
