New for the 2014 Season! The Yamaha Phazer 2007-2015 Replacement Header $399.95. You can now replace just the Header without buying the OEM Yamaha $1100.00 complete one piece Exhaust. Easy installation Instructions. We feel the main cause of Premature OEM Flex coupler Brakeage is the Header Sub Frame mount is not located correctly, which in turn the Header Flex Coupler is not in a Neutral Position and not leaving enough room for Heat Expansion causing the Coupler to fatigue and crack. We have Moved the Bracket back 15.00 mm allowing Flex Couplers to be able to move freely back and forth under running Temperature changes. The Header is Manufactured out of 304 Stainless Steel and Tig welded. After many Hours of testing and Dyno Runs we are not claiming any Extra HP because there isn't any to be had with a Header for Yamaha Phazer Model. Available in October

Excell Motorsports X Wheels
Excell Motorsports has designed a 135.8mm idler "X" wheel for Yamaha Snowmobiles
that will replace the stock (or Yamaha Accessory) 129.37mm wheels on all 2006 to
2014 Apex, Vector, Venture, FX Nytro, and Phazer models. Excell Motorsports has
tested the 135.8mm wheel for over 2 years with major benefits in slider wear and
longevity. The "X" Wheel is solid with no holes to help combat freezing of the
wheel in place. It is also a direct bolt on replacment with no need for longer
bolts or machining of the mount to make it fit. It is a direct replacement wheel
for inside or outside the rail. The "X" wheel comes with the replaceable 6005
$29.95 for a complete wheel ready to bolt on! Available now!

Introducing The New 2014 Yamaha SRViper Hi-Flo Excell Header
Excell Motorsports is extremely excited to release the very first “sneak peek” of our Yamaha Viper Preproduction Exhaust Header. Since we had the FXNytro 1049cc Header pipe dialed in for maximum HP and torque, this project was a bit of a challenge attempting to get Equal Tube Length and what we know into this new snowmobile chassis. Header Tube Length is so important that 1-2 inches the wrong way in any direction can Hurt your desired HP/Toque Numbers. But at the same time we finally had the room to run our Favorite "TRI" High Flow Merge Collector with new 308 .049 stainless wall thickness.
While riding the Viper through rough trail conditions with "Go-Pro under the Hood", the video footage of the Stock OEM Header showed flex from the chassis/engine and silencer mounting. So, we too decided not to cut costs and to run a flex coupler just as the OEM's are currently using on their stock header.
We will be heading to www.dynotechresearch.com next week for some long awaited Dyno time with the new Yamaha Viper in conjunction with Excell Header, Power Commander 5 "Excell Maps" and air box modifications after more Field testing this week. Excell Viper Exhaust will be available in header to stock muffler and header to Excell Silencer for closed course racing.
