Question about a NX4's muffler

[Ontaeronut]

Hi folks,


I am wondering if anyone can help me with a question about the Gaui NX 4's muffler. I am talking about the one that comes from Gaui. Could anyone tell me the length of the "manifold" the part that bolts to the OS37. I need to know if it will be long enough to clear the fuel tank on my heli. I am looking for a muffler for a 37 and it's down to either the Gaui or Hatori... and I like the price of the Gaui one...

Thanks

What exactly do you mean by clear the fuel tank? Do you mean the length? I have the gaui pipe on my nx4 and everything works out good.

The pipe is not being used on a Nx4, it's going into another brand. So I need to know the length of the part of the muffler that bolts to the engine. From it to the backside of the pipe.

I can't get an exact measurement cause mine is mounted. But it is around 26-27mm.

Acually that works, thank you
