|Yamaha Nytro Double Step Header Pipe
We have developed a new header pipe for the Yamaha Nytro which delivers an additional 8 hp. The first section of the header pipe is
increased from the stock 1.375" o.d. tubing to 1.5" tubing. Halfway up the collector junction the tubing is increased to 1.625".
This extra flow area results in an extra eight horsepower increase at the 8600 rpm power peak, and an 11 hp increase past the power
peak at 9200 rpm making the power curve almost flat all the way to 9200 rpm. Torque is improved by 8.4 lb.-ft. at the power peak.
This is the most powerful header pipe you will find anywhere for a Yamaha Nytro, and a great choice for a performance increase if you
want to run the stock muffler. The header pipe is designed from deep draw steel and silver ceramic coated for protection against the
heating and cooling cycles from snow hitting it. If the header pipe is used in conjunction with the Mega Power Silencer, total power
increase is 14 hp, bringing peak power to 157.8 at 8600 rpm. If both are used together, a DYNO JET EFI Tuner should be installed in order
to richen up the fuel mixture.

A right angle end piece is now available to direct the exhaust up or out the sides for those who wish to install an extra tank can or accessory bag.
Yamaha NYTRO FX With AAEN Mega Power Silencer:
The Yamaha NYTRO FX is Yamaha's Best four-stroke effort to date. The Yamaha NYTRO FX is both light and powerful, and is the basis
for Yamaha's Sno-Cross factory effort. The Yamaha NYTRO FX stock horsepower peaks at 138 hp at 8600 rpm, with such a long power curve
that the torque peak is 90 lb-ft below 7500 rpm.
The Aaen Mega Power Silencer is constructed from steel and is silver ceramic coated both inside and out to take the abuse of constant
heating and cooling cycles as it is showered by snow from the track. The 4" body houses a 2.5" core, and is packed with the best
grade four-stroke fiber silencing material. The silencer is quickly rebuildable by removing the billet end cap, which is fastened
with six screws. A red anodized end plate sandwiches in place the chrome outlet tube, and the removable "quiet core".
The Mega power silencer produces 144 hp at 8600 rpm, and max torque is above 93 lb-ft below 7500 rpm. This is a 6 hp increase over
stock with an additional 3 lb-ft of torque. With the "quiet core" installed, the power peaks at 142.5 at 8500 rpm, with 92 + lb-ft of torque
below 7500 rpm. With the "quiet core" installed, sound level drops another 4 dB (A) (40%). The Aaen Mega Power Silencer for the
08 Yamaha NYTRO FX is 7 lbs. lighter than stock and is a direct bolt-on in place of the stock muffler. An additional bracket is
included to hold the rear plastic cover in place.
The extra power and lighter weight adds increased excitement to the 08 Yamaha NYTRO FX and with its quality construction,
quiet core and easily rebuildable features, the Aaen Mega Power Silencer should make it a hit for both racing and trail riding.
