Product Description
3" Highflow Top Hat & Map Pipe - Dump Valve Model for Vauxhall Astra VXR
The TX Autosport 3" Highflow Top Hat & Map Pipe (Dump Valve Model) is a performance-focused upgrade for Vauxhall Astra VXR enthusiasts. Designed as a direct replacement for the standard top hat, this highflow kit enhances airflow, throttle response, and sustained power throughout the rev range, delivering a significant performance boost for both standard and modified vehicles.
Featuring a 76mm (3") stainless steel top hat, this component provides a larger diameter and better flow than the restrictive stock top hat. The increased airflow de-restricts tight bends, allowing the engine to breathe more efficiently. The kit also includes a 57mm (2.25") map sensor pipe, a silicone dump valve connector with clamps, and a silicone reducer, ensuring a secure and reliable fit.
Quick and easy to install with just an 8mm and 10mm spanner, this Top Hat & Map Pipe kit is ideal for those looking to optimise their Vauxhall Astra VXR’s intake system for improved power and performance.
