Product Description
TMRTR-TS1100
Complete Twin Scroll Turbocharger Setup
Discover the new GTX2971 Twin Scroll Turbo system with TR Equal Length Exhaust Manifold, Up-Pipe, and High Flow Catless Downpipe—engineered for a true twin scroll turbocharged experience on WRX and STi models. Rated for approximately 430whp, twin scroll technology transforms spool speed for quicker, more responsive acceleration compared to single scroll turbos.
Advanced Turbo and Exhaust Technology
This setup uses a ball-bearing cartridge and a lightweight billet compressor wheel, housed in a 10cm² turbine. Each blade is point-milled for maximum airflow, featuring unique wheels that are 20% larger and 17% longer than factory designs. The polished exhaust housing minimizes turbulence, while all necessary installation hardware comes included for a smooth upgrade.
Durable, Direct Fit and Fast Installation
Designed for Subaru enthusiasts, the twin scroll system is a direct bolt-on solution for 2002-2007 WRX and 2004-2018 STi models. The high flow catless downpipe, made from SUS304 stainless steel, features enlarged piping and ported flanges for faster exhaust air flow and lasting durability. Equal length headers with lost wax finish and three-bolt flange design ensure reliable connections with simple OEM fitment, so all components install easily in their stock locations.
