Muffler is nice looking. Seems to have some tuned effect (engine seems to prefer a certain RPM).
The exhaust deflector with the cap is a nice gimmick, it works but you Always get your hands dirty, both opening and shutting it.

I noticed very bad leakage between engine and exhaust, that a new gasket did not fix.
Found the surface of the header to be VERY roughly machined, with burrs and scratches.
When I flattened and trued it, the leakage was gone.

Sound: not super quiet, but absolutely acceptable.

Maybe not the best out there, but for its price absolutely good!

PLEASE IGNORE THE CROWNS: I would give it 4 overall, vaule 4, and quality 3 at best (you should not need to true machined surfaces....)

Se monte sur mon os55 hz, il faut agrandir la bride d'entre pour aligner la lumire d'chappement.
Mon problme est que j'ai du meuler la face infrieure du chassis (t-rex 600 dfc) puisqu'au serrage, le dessous du pot est en contact et gnre des vibrations.

Purchased this muffler for a Trex 600 with OS55. Within three minutes of flying I landed to check the muffler bolt tension and noticed it was rattling. An internal weld had let go and a piece of metal was rattling around inside. Might be just a dud one I got but I wont be getting another. Absolutely no complaints with hobby king, they credited a refund to me within two days of my claim! Video link of muffler here http://www.youtube.com/watch?v=TCCgK3-eJYE
