Teryx4 H2 Header & Mid Pipe Upgrade Kit — High-Flow Ceramic System (99013)

Unlock more power, response, and airflow from your 2026 Teryx4 H2 with this high-flow header and mid-pipe upgrade engineered exclusively for the new H2 platform. This bolt-on system replaces the restrictive factory header with a long-tube, ceramic-coated design that improves exhaust velocity, reduces heat, and delivers smoother low-end torque and stronger acceleration.

Fast UTV verified this header kit with in-house dyno testing, confirming +11-wheel horsepower gains when paired with the full exhaust system. Even as a standalone upgrade, riders experience sharper throttle response, cooler exhaust temps, and an overall cleaner, deeper exhaust tone — all while maintaining OEM reliability.

This system connects directly to the factory muffler and spark arrestors. No tuning, cutting, welding, or fabrication required.
