Maintenance Tips

After every major off-road ride, let the entire Pro Circuit T-4 exhaust system cool completely before cleaning it. Use a soft cloth and a cleaner suitable for metal surfaces to remove mud, dust, and residue. Avoid using products that are too harsh on brushed aluminum. Regularly check that the fasteners are tight, especially after the first few rides, and monitor the condition of the internal wool: a well-maintained muffler retains a cleaner sound and better performance.
