Hey,

I'm flying my evo 50 with os 50 hyper and the stock Hirobo muffler.
I noticed this muffler is too weak and can't give enough power.

I want to get Hatori mufflr or Zimmerman. What is the best between the two ?

Thanks,
Gil.

Hi there.
The Hatori SAB50HP (Hatori USA) is fantastic! Lots of power, easy to tune.
