I've never tried it on a 50, but I didn't have much luck with the EVO pipe on my OS 55HZ...hard to tune, sound was raspy even when the engine was rich, power was down, etc..

I'm currently running the Hyper Rage pipe on my OS 55HZ...it's been fantastic! Easy to tune, great sound, and makes plenty of power.

If you want, I'll send you my EVO pipe for you to try out on your 50...

Wow the Outrage Evo 55 is hard to tune we ran couple tank tuning from a very experience guy. We got close to tuning and couple flight we'll have her tune. But it's a pain of a butt. A lot of engine shut off. A lot of tweaking the lowend needle. I don't recommend nobody to run this muffler. Chamber is a bit to big for os 50 hyper. I'm gonna get her tune right and post here how she fly. But not a good idea for OS 50 hyper. Maybe a YS 56 though. Chamber is where it lie the problem I bet. Simply to big.
