Description Trask Down Under Head Pipe for M8 models 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. Trask Down Under Head Pipe is constructed of Stainless Steel that 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. – FEATURES: High performance, cost-effective OEM replacement header Delivers superior flow, performance and durability Made from premium stainless steel tubing, TIG-welded and purged to ensure maximum strength, precision and long-lasting performance Mandrel bent for unrestricted exhaust flow CNC-machined exhaust port flanges for improved sealing and optimized exhaust flow Catalytic converter has been removed to reduce restriction and unlock the full potential of the engine – NOTES: Compatible with stock H-D heat shields and crossovers and extensions for Trike models.
