Install: Quiet Core & Spark Arrestor

Every HMF exhaust comes with a U.S.F.S. Spark Arrestor uninstalled. The installation process for the Spark Arrestor is the same for the Quiet Core and should only take a few minutes to complete. However, if you have an Elliptical exhaust with a Euro End Cap the installation process is slightly different. Click here to view the Euro End Cap instructions.

Installation Instructions:
1. Don't attempt to remove the End Cap if the exhaust is hot.
2. Remove the 3 allen screws that hold the End Cap.
3. Remove the End Cap.
4. Place the Quiet Core/Spark Arrestor in the outlet. (There is a machined lip for it to fit into) See Figure 1
5. Replace the End Cap. See Figure 2
6. Tighten the 3 allen screws and you are done.

Maintenance:
Check your spark arrestor screen from time to time to see that it is free flowing and not clogged.

The easiest way to clean the spark arrestor is to remove it from the exhaust then soak the spark arrestor in oven cleaner. Wait for a few minutes, then clean the remaining residue with a wire brush. Keeping the spark arrestor clean will increase exhaust flow and performance.
