I would say looking at that graph I could believe it. Look at the base line 138 hp to 152 is 14hp increase with a header muffler and tuner.....believeable
right from there site
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.

I am also interested in this. It would be awesome to hit that 160 hp mark with just a couple of add ons!

I'm not seeing anything over 151 on that chart... maybe somewhere else on the site??? 151 is believable... I think 160 is getting close to out of my thinking.

I doubt you will see anything near 6hp increase with just their silencer. This leads me to be suspect of a 14hp increase with both... just my .02

I agree, there charts don't match the article. I was just saying it would be sweet if we could reach those numbers without a ton of money invested and also still have stock reliability.

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.

well then 157 is clearly a misprint i take it. my question is still who puts the most power to the ground with a performance kit

the tuning is the key with this stuff..lots of parts available...but few who constantly tune...
the 157.8 is clearly a misprint.. 151 -152 is conceivable...stainless steel vs aaens carbon steel with a coating...although I like olav IMHO this isnt a good choice ...
excell and al ulmer have a turn key kit that will do what they say...even the clutching to match if you desire...
