hi,
i have a mvvs 150 engine with 45 deg exit.
when i put it on the plane the exit of the tune pipe is lower then the fire wall of the plane so i heat up the
adaptor of the tune and bend it a little.
when i started the engine the adaptor break to 2 pcs and then i fix it and its broke again in another place.
i think that the heat destroied the adapter strength becu its alominiom.

does anybody have an idea for me?

thanks
nir
