I know it's a little bit different but my SuperTigre 51 that I am running on gasoline gained 200 with the deflector. The muffler is the stock ST boat anchor. I don't normally run one so I tried just to see if it made a difference and that was the result.

I do run one on my Raptor 50 and it makes NO difference with or without. When I get some more time I will try my TT 40 Pro on my Viper and see how it reacts.
