YS Engine YSF8089 tube holder DZ170 spare part  [YSF8089]

Tube holder for DZ170

This tube holder is an RC-scale spare designed to secure exhaust tubing on DZ170-series model engines, helping keep routing stable during runs and maintenance. It serves as a straightforward retention point between the header and muffler assembly without affecting other engine systems.

Installation is focused on alignment and secure retention rather than performance modification: position the tubing through the holder, align it with the engine's exhaust outlet and existing mounting points, then secure using the vehicle's original fasteners or clamps. The part is intended to work with the mounting geometry of DZ170-compatible setups, so verify fit before permanent fastening.

In tuning and setup, a consistent exhaust path aids repeatability; this holder reduces movement that can change backpressure or routing during testing. Use it as a maintenance and routing aid when swapping mufflers, adjusting pipe angle, or preparing an engine for bench or track evaluation.
