Reds racing 2104 pipe and manifold S kit for .21 / 3.5cc rc nitro engine.
Part number: KM212104 S.
I use graphite grease between pipe and manifold and between manifold and engine, i learned that tip from one of the Ty Tessmann's video.
Reds manifold have certain bending so it fits perfectly with Reds engine. Angle between manifold and pipe is odd / bad when using other brands manifolds with Reds engine.
