Hi, I am upgrading my Raptor 30 V2 to a 50 V2. I am planning on putting the O.S. 50 Hyper in it and was wondering what the best muffler to squeeze the most power out of this puppy would be. The CY muscle pipe? http://helihobby.com/html/pipes_mufflers.html .

Or any other that you guys would recommend.

Noise is not a problem

Thanks, Alex
