Provide an 8 - 10% horsepower gain.
Tunable Disc Technology: Feature the tunability of SuperTrapp's patented diffuser disc end cap system with adjustable back pressure and noise level.
Adjust sound levels and powerband by adding or removing 4" external discs:
Add 4" discs to increase horsepower, exhaust tone and flow.
Subtract 4" discs to reduce sound and increase low-end torque.
Megaphone Slip-Ons are compatible with SuperTrapp True Duals and the Crossover Conversion (both sold separately).
Optional Open End Caps (sold separately) for closed course competition are also available.
Includes 12 4" discs, rebuildable core and packing per muffler.
Made in the U.S.A.
Note: Sound test data on 2010 and up model-specific slip-ons was achieved using the O.E.M. 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.
