The classic Megaphone design allows the exhaust gas to expand which increases power. Discs let you control the flow. Optional Open End Caps for closed course competition are also available.

Twelve - 4” discs, a Closed End Cap and all necessary mounting hardware is included with Slip-Ons and the 2:1.

Twenty-four - 4” discs, Closed End Caps and all necessary mounting hardware is included with the 2:2.

Add 4” discs to increase horsepower, exhaust tone and flow.

Subtract 4” discs to reduce sound and increase low-end-torque.

Note: Sound test data on '10 - '13 model specific slip-ons was achieved using the OEM CAT equipped headpipe. Use of these mufflers on headpipe with the CAT removed or True Duals will result in substantially louder results. Optional cores are available for certain models at an additional cost.
