Recommended exhaust for a OS37 Gaui NX4

[liamm =D]

While flying my gaui nx4 today The ground jumped out of no where and it went in a little too hard and I have managed to snap the exhaust for the OS37 on my Gaui NX4 LOL.

Anyway I don't mind buying another Gaul one as it worked well but are there any better alternatives that help produce more power or make it run smoother ? I know hatori do one and Zimmerman (if you can get old of a Zimmerman )

has any one used any of these ?

thanks Liam

The hatori is by far the best pipe for the 37, got mine from RCJapan but try midlands think they had some on sale.

Try motors and rotors or probuild for hatori and Zimmerman

I've got 3 dead gaui pipes here, all fractured through the weld in the same place.
1 hatori 415 that still looks and feels like new.
There's 3 different hatoris that fit,415,416 and the 37ns-3d is the most popular and I believe designed for the nx4.
There doesn't appear to be any performance gain 415 but it does idle smoother and sounds a bit nicer, the overall quality is the bit that makes it worth every penny!
