I have purchased a used DR650 with a 'racing core' SuperTrapp exhaust. What is the difference between the racing core and the quiet core? Can the racing core be made quiet?

The difference between the IDS2 Race Core and Quiet Core are that the Race Core has tunable discs and a closed end cap. The Quiet Core has sound absorbing material, a rebuildable core, a primary baffle, a secondary baffle and exhaust passage. The baffling in the Quiet Core is what makes it such.

Both cores are interchangeable, so you can purchase our quiet core for your IDS2. The Race Core was designed to be loud, therefore, there's not much you can do to quiet down your Race Core.

Hope that helps.
