RPM RZR XPT E-Valve Muffler
Want to control the sound and performance of your RZR at the flip of a switch? The trademarked RPM SXS E-Valve Exhaust System delivers complete sound control on demand!
Keep the electronically controlled valve closed for a deep, smooth, performance sport exhaust tone—or flip the dash switch to open the second 2.5" dump outlet for raw turbo whistle, aggressive exhaust roar, and maximum exhaust flow.
How It Works & Performance Gains:
Built around our high-flow, catless Sport Muffler core, this system incorporates a secondary 2.5" bypass tip positioned directly at the exit of the mid-pipe. When opened, it bypasses internal muffling to create an unrestricted, straight-through exhaust path.
-
Valve Closed: Clean, deep sport exhaust tone with a proven +3 HP gain over stock.
-
Valve Open: Maximum turbo flow and aggressive sound delivering +7 HP gain and +500 RPM over stock!
By eliminating the restrictive factory catalytic converter, this exhaust system drastically reduces exhaust gas temperatures (EGTs) and engine bay heat buildup.
Customizable Finish & Plug-and-Play Wiring:
Constructed from heavy-duty, TIG-welded stainless steel for extreme off-road durability, each system includes your choice of an RPM logo backplate color (including raw aluminum for custom powder coating). The system comes complete with a pre-wired plug-and-play wiring harness and illuminated dash switch for an easy, seamless installation.
