Supertrapp S/C Standard have a deep, agressive tone and are tuneable. Fewer discs reduce sound levels, and added discs increases sound levels.
You can adjust your power band : fewer discs will tend to increase low-end torque and richen carbureted fuel mixture: more discs move the powerband up to give you more top end power, and leans out the carbureted fuel mixture.
These mufflers increase power because they are a straight through design which makes them very efficient. Stacked disc design also helps scavenge hot exhaust gases for maximum performance.
Supertrapp Mufflers are re-packable, (See replacement parts section.
