Fitment and maintenance notes

This RC exhaust pipe set is produced for compatibility with the O.S. Engine FS models listed. The 60 degree bend is intended to complement the exhaust pulse characteristics of FS-40, FS-61, and FS-80 engines so tuners can refine back-pressure and routing without internal engine changes.

The components are provided as replacement or upgrade parts for tuned-pipe systems. Fitment aligns with FS-series manifold outlets and mounting points; confirm manifold outlet spacing and gasket seating before final torque. Standard hand tools cover installation, and flange fasteners should not be overtightened to avoid damaging sealing faces.

Used in a tuning setup, this pipe influences pulse scavenging and midrange response. Plan for carburetor and possibly header length adjustments after fitting to maintain the desired power delivery.

Do I need new gaskets when fitting this pipe?

It is recommended to inspect or replace gaskets during installation. A flat, undamaged gasket surface ensures a proper seal and prevents exhaust leaks at the flange.

How can I avoid overtightening the flange bolts?

Use controlled, incremental tightening and check for uniform gasket compression. Hand tools and a sensible torque approach will prevent distortion of the flange face.

What should I watch for in service life?

Monitor flange seals and mounting hardware for signs of loosening or corrosion. Regular checks after initial running will catch installation issues before they affect performance.
