Chrome. The Eliminator 400 Slip-On series are mufflers for those that like the massive look of round 4″ large diameter mufflers, but the Eliminators offer more than looks. These large diameter slip-ons help achieve a higher volumetric efficiency, which creates a better cylinder fill to help get more performance from the engine. The sound-tuning at Vance & Hines is of an identical quality level as the exhaust system and designed to give that deep, aggressive roar. With race-inspired end-caps. Optional quiet baffles are available for sound-level tuning. Note: Will fit extended saddlebag skirts. Note: Optional quiet baffle available as 586189. Note: Shown in combination with Vance & Hines Power Duals head pipes.
