1. What is the tailpipe shape?

The proper fitting nozzle is based on the shape of your tailpipe.

2. What is the tailpipe O.D.?

Measure the outside dimension (O.D.) to determine the width of the tailpipe.

3. What is the tailpipe protrusion?

To figure out how the adapter will fit on to the tailpipe it's important to note how the tailpipe/tailpipes protrude from the vehicle.

Older vehicles feature a tailpipe that protrudes from the body and requires a spring-clamp attachment while newer vehicles feature flush tailpipes that require a suction-cup attachment.

4. Do you have dual tailpipes?

Y-connectors are required to connect dual tailpipes.

5. What is the distance to outside?

Starting at the tailpipe, take down an accurate measurement of the distance to the outside.

6. Will your system be passing through a garage door?

If you're exhausting through a garage door you will need a door port to feed the hose through.

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.
