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

Tune pipe for Savage-series K4.6 engines

This alloy tune pipe is a dedicated exhaust part for the HPI Savage family of nitro trucks. Supplied as a replaceable assembly, it comes with the joint and mounting screws to match the K4.6 engine exhaust flange and the common manifold arrangement on Savage, Savage X and Savage XL models.

The component is intended to provide a durable interface for exhaust tuning, preserving backpressure and resonance characteristics during setup and running. Alloy construction limits distortion relative to softer materials, while the included fittings make post-maintenance reassembly quicker.

Fitment notes: confirm the engine outlet lines up with the tune pipe joint before tightening fasteners, hand-start screws to protect threads, and ensure mating faces are free from gasket debris. After initial running, check fastener security and exhaust sealing as part of standard maintenance.

Designed as an aftermarket swap for Savage chassis equipped with the K4.6 engine, this tune pipe delivers a simple replacement and improved part stability for exhaust tuning tasks.
