Advance Headers High-Flow Turbo Dump Pipe Solution for your SUBARU Boxer Engine
The Advance Headers 3" Turbo Dump Pipe (TWRX) is engineered specifically for Subaru EJ-series single-scroll turbo platforms manufactured between 1992 and 2013, covering the legendary Impreza WRX, WRX STi, and Liberty GT. Eliminating the massive restrictions of the factory casting layout, this Heavy-Duty unit ensures High-Flow Performance & Direct Bolt-On Fitment.
PRODUCT CONTENTS:
- 1 x 3" Heavy-Duty Mild Steel Turbo Dump Pipe (Standard Finish)
Key Features:
- Heavy-duty mild steel construction engineered structurally tough to handle high under-bonnet boxer thermal environments
- Massive 3" primary pipe layout immediately clears restrictive exhaust backpressure straight off the turbine wheel exit
- Drastically reduces turbo lag, dramatically optimizes throttle response, and maximizes top-end power output
- 100% direct bolt-on path designed to mate up cleanly with factory-style single-scroll turbochargers
- Thick precision laser-cut base flanges resist thermal warping to guarantee a permanently stable, gas-tight exhaust seal
Specifications:
- Brand: Advance Headers
- Part Number: TWRX
- Primary Pipe Size: 3" (76mm)
- Material: Mild Steel (Standard Finish)
- Turbo Compatibility: Single-Scroll Turbos Only (Will NOT fit Twin-Scroll setups like VF38)
- Welding Required: No
⚠️ Crucial Fitment & Modification Notes:
1. Twin-Scroll Exception: This dump pipe is explicitly built for single-scroll turbo systems. It will NOT fit models configured with a factory twin-scroll turbocharger layout (such as the VF38 or JDM twin-scroll setups).
2. Subaru Liberty Automatic Models (2007-Onwards): Vehicles falling into this profile configuration will require a slight clearance mounting modification at the time of installation to ensure perfect underbody positioning.
Please Note: Professional installation by a qualified mechanic or exhaust specialist is highly recommended to guarantee proper alignment and a perfect leak-free seal.
