I have friend running Funtech 300 on YS91st that making great power and is quieter than my 3ds/SB19FB but it's not making 3DS power.

If i'm not mistaking the 300 is the newer pipe.

I was using a SZ-H 91 with K&S muffler and this combo was making good power. Recently I changed my engine for an HZ-R with the same muffler and the power was ugly so I went with the Funtech B300 and I couldn't believe the difference! Now my engine has become a beast! Really huge difference. There is a new Funtech muffler (rigid)called B301 that I have tried at my local club on my Friends heli (Raptor 90)Power is also really awesome and he told me that it produce much more power than the previous B300 version

Ive had good and not so good experiences with the B300.

The good:

I had it paired with an OS91-HZ and it produced lots of power. It produced almost the same amount of power on a YS91-SR. Believe it when you hear that its a quiet muffler. Or should I say not hear it? LOL

The bad:

The red side mounts are WEAK. I had both of them come apart in the same area. The outside plate is too thin and if you have vibrations coming from the motor it will start to wear those mounts down quickly. Also, If you run them on OS motors, the YS mounting holes will expose a tiny gap at the exhaust port. You will have oil leakage. I think an OS gasket will cover it, you will have to find out for yourself.

If you are looking to buy it brand new then I would recommend spending a little more and get the Hatori pipe for your motor. If you are doing 3D, you won't be happier with any other pipe. Trust!
