ASM .21 Headers
ASM .21 Headers - Precision Engine Tuning for Every Track Condition

ASM offers a wide range of high-performance headers to fine-tune your engine's power output, enabling you to optimize your vehicle's performance according to track conditions. Each ASM manifold is designed with precision, providing unique characteristics suited for specific speed and torque needs.


ASM 26 Manifold Short

Ideal For: Low to Medium Speed Tracks

  • Description: A short manifold that mirrors the shape of the ASM 28 manifold but is 2mm shorter for improved response.
  • Key Feature: Higher rotation, perfect for quick handling and tight turns on low to medium speed tracks.

ASM 28 Manifold Torque

Ideal For: Low to Medium Speed Tracks

  • Description: Torque-focused manifold designed for smooth acceleration and power delivery in lower to mid-speed ranges.
  • Key Feature: Specifically engineered to maximize torque output for a smooth and responsive engine feel.


ASM 32 Manifold Torque Medium

Ideal For: Balanced Torque & Speed

  • Description: A medium-length manifold that balances between high torque and high-speed capabilities.
  • Key Feature: Offers a versatile setup, giving you a combination of smooth low-end torque and mid-range speed for dynamic racing.


ASM 32W Manifold Torque

Ideal For: Mid-Range Speed Enhancement

  • Description: Slightly shorter than the ASM 32 manifold, this model offers a minor RPM boost, ideal for higher mid-range speeds.
  • Key Feature: Slight increase in RPM compared to the ASM 32 manifold, making it perfect for slightly faster tracks.


ASM 34 Manifold Torque Long

Ideal For: High Torque, Longer Tracks

  • Description: 2mm longer than the ASM 32 manifold, providing a noticeable increase in torque for long, sweeping turns and straightaways.
  • Key Feature: Extended torque range, perfect for high-speed tracks requiring smooth, sustained power.


ASM 226 Manifold Short

Ideal For: Medium to High Speed Tracks

  • Description: A straight type of header designed for higher RPMs and a quicker throttle response.
  • Key Feature: Optimized for medium to high-speed performance, allowing for sharper acceleration and handling on faster tracks.


ASM 228 Manifold Medium

Ideal For: High-Speed Tracks

  • Description: A straight type header built for maximum high-speed performance.
  • Key Feature: Provides efficient airflow and a higher top-end speed for vehicles used on fast, open tracks.
