2008 Yamaha NYTRO FX With AAEN Mega Power Silencer:

The 08 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.
