The tube holder is an RC-scale accessory intended to secure exhaust tubing on DZ170-series model engines, keeping routing steady during operation and maintenance. It provides a direct retention point between the header and muffler while avoiding impact to other engine parts.
Installation focuses on alignment and secure retention rather than tuning: pass the tubing through the holder, align with the exhaust outlet and existing mounting points, and secure using the vehicle's original fasteners or clamps. The piece is designed around DZ170-compatible mounting geometry, so confirm fit and clearance before permanent fastening.
Maintaining a consistent exhaust path aids repeatable setup; the holder helps prevent movement that can alter backpressure or pipe direction during testing. Employ it when swapping pipes, altering angles, or preparing the engine for bench checks or track work.
