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.

We had a Very Educational Day at www.Dynotechresearch.com yesterday Jan. 23, 2014 with the New 2014 SR Viper. We didn't know how Spoiled we were with Decent Flowing Air Boxes and Silencers. The SR Viper is a Totally different Beast to Gain H.p than the Fx Nytro is . After a full day of testing various Components we did make an extra 15.5 HP with a Torque gain of 8.6 . The Average Stock Baseline of 132.2Hp and with Excell Goodies made 147.7Hp. Unfortunately we found Very little Extra H.P. with the Current OEM Stock Muffler and Current Air Box Configuration with any Header Configuration to warrant the expense so far. Also we did defiantly see the need of a PC 5 because of Very Lean Midrange AFRís with Air Box Mods and Slip on Silencers even with the Stock Header. Bottom line is we are not happy enough with Results to put anything into Production just yet. We have started working on a Complete New Air Box, Individual Air Filters and New Quiet Silencer For our Next Visit to Dynotech. At the same time Field Testing so we can make certain Excell Performance Product's work the best for our Customers.
