Down Under Replacement Head Pipe

The Trask Down Under Replacement Head Pipe is designed for riders who demand performance, durability, and precision fitment. Built to outperform stock systems, this head pipe delivers superior flow, increased horsepower, and long-lasting reliability. 

Stainless Steel construction which is TIG welded and purged to ensure smooth airflow and maximize strength. Unlike stamped factory parts, the machined port flanges provide a tighter, more positive seal at the heads, reducing leaks and optimizing exhaust performance. Stainless steel construction not only enhances durability but also dissipates heat far better than stock, keeping performance consistent under demanding conditions.

For even greater gains, the catalytic converter has been deleted, freeing up exhaust flow and unlocking noticeable horsepower improvements. The Down Under Head Pipe is also designed to work with OEM heat shields (not included), maintaining a clean, factory-style fit while delivering serious performance upgrades.
