I really don't know if this is info, but Novarossi is a long time brand. Made in ITALY... Also I own cars as well, and they have novarossi's in them. They are very good. The pipe I heard with the engine sounded like a yamaha...Jeffrey Fung...15 Years old - FLEET: Evo 50, Raptor 30, Trex 500, SDX's, X-Spec, Logo 10/400

If you want all the power the nova can give you need to run the nova pipe.
All other pipes are tuned in the 15,000 rpm range and the nova runs well above that about 18,000 to make full power which means your rotor speed should be about 2200 rpm.
Have run both the nova and the os 55, tuned 4 nova 57 motors here, and if you fly hard the nova is fine but requires constant glow plug and needle changing as the seasons change, they are very temp. sensitive. Am flying the 55 right now and it makes nearly the same power as the 57 at a much lower rpm. although nothing makes as much power as the 57 if it is tuned properly with the nova pipe.
Knowing what i know now if you just want to set it and forget it use a different motor but if you want all the power you could ever need but at a much higher rpm then go nova.
The only other info i can give is both the nova and the os put exhaust into the fuel system which can cause fuel line and pickup problems over time the ys 56 does not use exhaust pressure but uses crankcase pressure in the fuel system and is another good engine to look at.

Split the difference and get a better engine.
YS 56
More power than the 55
More consistent than the 55 or the 57.
The mufflers of choice are the Outrage, Funtech or Hatori designed for the 56.
