O.S. Engine OS26625510 Extension Adaptor E-4011 GT15HZ for RC Exhaust Systems  [OS26625510]

Exhaust extension adaptor for radio control engines

This RC-scale extension adaptor provides a compact method to extend or reposition exhaust piping on model engines, intended as an accessory for exhaust and pipe assemblies rather than a standalone engine component.

Functionally the adaptor serves to move the outlet position or increase clearance between the pipe and nearby components, making it useful when customizing pipe routing or fitting aftermarket mufflers on models where space is limited.

Installation is straightforward for hobby technicians familiar with engine plumbing: align the adaptor to the existing exhaust outlet, engage threads or mating surfaces carefully, and tighten progressively while checking alignment and clearance. Use the engine manufacturer's guidance for recommended torque and sealing practice to avoid leaks.

For tuning and setup, the adaptor allows incremental changes to pipe length and exit angle which can affect backpressure and packaging; use tested configurations and incremental adjustments when evaluating performance or fitment on an RC chassis.
