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

Compact exhaust outlet extender

This extension adaptor is a compact solution for lengthening or repositioning exhaust piping on model engines, intended to work with exhaust and pipe assemblies rather than acting as a separate engine item.

The adaptor is useful for increasing clearance around mufflers and pipes, or for altering where the pipe exits to avoid nearby components. It is particularly handy when adapting aftermarket mufflers or rerouting piping on tight installations.

Installation is manageable for those comfortable with engine plumbing: align the adaptor with the engine outlet, engage mating surfaces or threads carefully, and tighten in small increments while checking alignment and clearance. Use the engine manufacturer's guidance on torque and sealing to avoid seepage.

When tuning, bear in mind the adaptor can slightly change backpressure through adjustments to pipe length and exit angle; make small changes and evaluate performance on the chassis.
