Hi, i dont have am os55 but was thinking of getting this engine, i have read through all the review of what pipe to put it in, for a good power get the os power boost, for the good quality get the hatori, the most best pipe today is funtech 392b if am not mistaken for the best price is outrage 55 56 big bore 50, and four the look and ruggedness get the the nova h5 hehehe anyway that was just my opinion, but on my experince the hatori will never let u down, most people has said that u can use the 50 pipe but it will reduce the performance due to less back pressure soo the power band was not fully achived IMHOTrex 600,700 AND 450, GY611, GY401, OS5H, OS91HZ, MGP, HS65HB, Scorpion 2221-8,

Most (all?) 50 pipes will work fine on the OS 55 including the Align pipe. However, some of the "best" going today include the OS Powerboost, and the Hatori SAB-55. Bear in mind that the Funtech A395 is identical to the OS Powerboost (literally just stamped with a different brand) but it's a little cheaper. It's what I run and also a lot of the big guns (e.g. Bert Kammerer).Sponsored by CSM and QuickUK

Correct me If I am wrong but I believe you guys are refering to the B320 by funtech, the 395 is for .50 OS

The A395 has been tested on the OS 55 and gives great results. An example of this can be seen when watching Bert Kammerer fly his 600. Again, it's the OS Powerboost pipe (which was essentially designed for the both the OS 50 and 55) but with a different name stamped on it. I have heard that the B320 also works well.

The 55 is still a 50 "class" engine and I have heard of many pilots running their stock Align pipe with very good results. Any decent powerfull 50 pipe will do the job and I don't think pipe selection is as critical as many have made it out to be with the new 55.

OS55 with Outrage
OS 55 with OUTRAGE HYPER RAGE 55 Muffler is also a great combo and great price too.
Thanks Long

I have had great success with the os55/GP55 exhaust in my 600. This combo is a powerhouse and very easy to tune.

There are a number of mufflers that tnbulldog and I have found to work through actual flight testing and they are:

http://www.heliwholesaler.com/A395-...oductinfo/A395/

http://www.helidirect.com/hatori-sb...yper-p-7465.hdx

At the moment I'm running the B320 which Sensui designed expressly for the OS55 but the A395, the Outrage 55 pipe and the Jason Pipe are strong runners. The Outrage 50 pipe works but I don't think it breathes as well as the later version while the later version sounds different.

I should think the Align 50 pipe would be fine on the OS. I'm having good results from the Align 50 pipe on a YS 56. I know it's a different animal than the OS 55, but the YS seems to breath OK and is making great power. I do believe that one of the purpose built pipes would give, at least, slightly better results, but it's what I had so I pressed it into service.

Any thoughts on the GP brand of pipes for the OS 55. I bought one, got a pretty good combo deal on it with the engine, so I figure I would try it out. The salesman said it has a deeper sound than alot of the other 50 size pipes and it makes great power. Its probably going to be a while before I fire it up though. Just wondered if anyone else has tried, seen or heard one of these in action.

I believe the 521 has been on the market for about 2 years or so, so it was before the OS 55. It's a one piece muffler. Here's what it looks like.

I don't see any reason it won't work. It looks like the one piece SB50.

Im using a Hatori #522 on my OS55 and its working very good. I like the 522 better than the Funtech 395. I think the only difference between the 521 and the 522 is the header on the 522 in 9mm longer.http://www.jaxrc.com
