MPI’s new Nytro Exhaust System is  two versions of the RX-1 lightweight exhaust system. 

11dB Louder with an 11lbs savings

The High Performance MPI Nytro Exhaust System saves weight but increases dB levels. The new exhaust system weighs just 4.75 pounds, with the OEM system weighing over 17 pounds. It was designed for use on Stock and Supercharged units. As this system has significantly less backpressure than the OEM system, Turbo should consult their kit manufacturers, as the increased flow and reduced backpressure will likely be detrimental to a turbo's performance. The system is made of 100% stainless steel and exits through the stock cowling behind the seat. The unit includes a billet aluminum tip.

FEATURES:
 - 100% 304 Stainless Steel Construction (including brackets & internals)
 - Complete Unit Weighs less than 5 pounds
 - Billet Aluminum Tip
 - Mathematically designed "Quiet Core" inside the Muffler to reduce noise, not flow.
 - 100% TIG Welded
 - Increased Exhaust Flow
 - PLEASE NOTE: This unit is louder than OEM, but is not ear piercing.

This kit can be used with or without the OEM radiator. This makes it possible to shed even more weight from the snowmobile while still enhancing the overall cooling system. This is no little cooler. The actual extrusion measures just over 8 feet long. YES!  E I G H T  FEET. Compare this to the OE tunnel cooler that isn't even 2 feet long!!

Performance improvements are HUGE! Typically 60 degrees cooler with our tunnel cooler and the OE Radiator. Typically 40 degrees cooler with our cooler only (that's you eliminating the OE radiator and OE tunnel cooler).

•  Our XTX Nytro (stock radiator and No OEM Tunnel cooler) ran typical temps over 200deg. WITH OUR NEW COOLER AND THE OE RADIATOR our max temps are 150deg and 110deg in the powder (actually to cool). We are going to pull the OE cooler on this unit.

• Our 2010 MTX Special Addition (stock radiator and OEM tunnel cooler) ran typical temps close to 200deg. With our new cooler only (deleted the radiator), our max temps are 160deg. The sled without the radiator actually idles cooler because without the sled moving, the OE radiator is actually adding heat.
  
  FEATURES:
   - Best Heat Exchanger Design Available. 8 feet in length!!!
   - 100% Tig Welded & Pressure Tested
   - Works with Stock and most Aftermarket Exhaust Systems
   - Includes Hoses, Clamps & Rivets. Everything required.

The Radiator delete kit includes a degas bottle to help keep the air out of the system and provide a location for filling. It uses the OE Yamaha radiator cap.
 

MPI’s newest add on for the FX-Nytro Supercharger Kit. Works on all 2008+ Nytro models, including MTX, RT, RTX, XTX.

High Performance MPI Nytro Cold Air Supercharger Intake fits conveniently under the hood. In extreme circumstances the unit may be routed through the hood, but testing has shown that simply rerouting the intake to the protected area over the clutches is sufficient to provide good clean dry cold air. The kit is easy to install, but does require that you remove your intercooler to access the supercharger inlet. A template is included to drill a hole in the left side bulkhead (testing shows no effect to structural rigidity of the bulkhead. Includes Fabricated mandrel bent 2.5" aluminum air tube, new filter and all hardware required for installation.

FEATURES:
 - 100% 6061 Aluminum Construction
 - Complete Unit Weighs less than 1 pound
 - New Mesh Filter included
 - Testing shows this kit ADDS 1 TO 2 POUNDS OF BOOST when working the unit hard.
 - 100% TIG Welded
 - Increased Air Flow
