DBR rock wool is specifically designed for DBR silencers in the 250/300cc off-road range. For other models or brands, we recommend checking the dimensions and compatibility before purchasing.
DBR rock wool provides optimal sound absorption, high resistance to heat and vibration, and maintains engine performance without compromise. The interwoven mineral fibers ensure long-lasting durability, even under extreme conditions.
Installation is simple: remove the old sound-absorbing material from the silencer, insert the new strip of DBR rock wool by wrapping it around the inner perforated tube, and close the silencer. No modifications are required.
We recommend replacing the rock wool every 20–30 hours of intensive use or whenever you notice an increase in exhaust noise, to maintain optimal performance and sound insulation.
