HPI Savage K4.6 Tune Pipe Alloy Replacement SAV1308R by GPM  [SAV1308R]

Aftermarket alloy tune pipe for Savage K4.6

This alloy tune pipe is an exhaust replacement part made for the HPI Savage family of nitro trucks. It is supplied as a replaceable assembly with the joint and mounting screws to match the K4.6 engine exhaust flange and the manifold layout found on Savage, Savage X and Savage XL variants.

The component is intended to provide a consistent mating surface for exhaust tuning so backpressure and resonance characteristics remain stable during setup and running. The alloy body reduces deformation compared with softer materials, and the included joint and screws make reassembly after servicing straightforward.

Fitting notes: confirm the engine outlet lines up with the tune pipe joint before tightening, hand-start screws to prevent cross-threading, and keep mating surfaces free of gasket fragments. Re-inspect fastener security and the exhaust seal after initial runs as part of normal model maintenance.

As an aftermarket option for Savage-series nitro setups with the K4.6 engine layout, this tune pipe provides a direct-fit replacement and solid part-level durability for exhaust tuning tasks.
