Question: What’s the best exhaust for YFZ450R? I bought a Yamaha four-wheeler ATV. It has the stock quiet muffler. It needs to be louder with a slip on muffler and make more power.

6 top slip on exhausts for the YZF450R

Dasa exhaust YFZ450R

  • All Dasa exhaust systems are handmade in the USA and the quality really shows with perfect tig welds, trick billet end caps, a billet canister mount, thick head pipe flange and the end caps do unbolt for easy canister repacking. This exhaust system has been proven on the dyno to make big HP throughout the entire power curve. This is a multi-step, stainless steel exhaust system that includes a head pipe, mid pipe, and an exhaust canister.
  • The Vortex is like our and EFI Interceptor rolled into one module. The controls not only Spark timing and Voltage output but also Fuel Metering and other engine management functions. The result is more power, better power, easier starting and ultimately faster lap times. This unit comes pre-programmed with 10 Performance Fuel & Spark timing maps as well as having 3 additional switches for user trimming (adjusting) of Fuel in Lo, Mid and Hi throttle openings.
  • The plugs directly into the bikes standard wiring harness and interfaces with all the standard engine sensors such as ECT (Engine Coolant Temperature), IAT (Intake Air Temperature), MAP (Manifold Absolute Pressure), TPS (Throttle Position Sensor), CPS (Crank Position Sensor) to adjust fuel and spark timing for optimum power delivery in all weather, altitude and load conditions.
  • Performance gains vary depending on throttle and RPM points however typically gains are in Top End power and Bottom End throttle response is expected from the Power settings and a smoother more tractable or rideable power from the Traction settings. We have done extensive work to include tune parameters which improve starting and almost eliminate the flameouts experienced with EFI mx bikes.
