Refine Engine Output with a Polished Manifold

The Tamiya 41074 - TM-2 Polished Manifold is a tidy upgrade aimed at improving the exhaust path on TNS engines. By smoothing internal surfaces, the manifold encourages neater gas flow and can improve engine response under load. The polished finish also helps resist wear and keeps the component looking sharp after repeated use.

Benefits of Choosing the TM-2

Built for compatibility with Tamiya TNS engines, the TM-2 fits without major alteration for most standard installations. Reduced internal turbulence supports more effective scavenging and can contribute to longer term reliability when combined with suitable maintenance. It is a sensible mod for tuners who want steady, repeatable performance.

Specification Highlights

  • Material: High-quality polished metal for reliable durability
  • Compatibility: Intended for use with Tamiya TNS engines
  • Function: Enhances exhaust flow and overall engine efficiency
  • Appearance: Polished finish for a precision look

Is the TM-2 suitable for competition engines?

Yes, it is aimed at users looking for improved exhaust flow; it suits engines used in competitive settings provided the engine uses the correct TNS flange.

Will fitting this require changes to the exhaust system?

Most installations are straightforward, but check exhaust pipe alignment and seals to avoid leaks after fitting the new manifold.

Can the finish be polished further?

The factory polish is designed for performance and durability; further polishing is possible but not usually necessary and should be done carefully to avoid altering fit surfaces.

How should I check for leaks after installation?

Run the engine and listen for exhaust leaks, inspect the gasket area for soot, and re-torque fasteners if any seepage appears after the initial heat cycles.

Does the manifold change peak RPM characteristics?

Smoother exhaust flow can shift engine response slightly; any change to peak RPM will depend on the full setup and may require minor tuning adjustments.
