304 Stainless Steel Unequal Length Cat-Back Exhaust System

This system replaces the stock header and up-pipe, which are known limitations in the factory design, offering a solution that increases horsepower, boosts torque, and sharpens throttle response while reducing turbo lag. The unequal length design also contributes to a more aggressive and desirable exhaust note. Constructed from premium 304 stainless steel, this header and up-pipe features smooth mandrel bends and an increased piping diameter to minimize exhaust restriction. The unequal length layout is a key design element for achieving the desired performance gains and sound characteristics. The package includes all necessary zinc-plated hardware and new exhaust gaskets for a complete installation. Its stainless steel construction ensures durability and resistance to corrosion. This product is specifically designed for Subaru models, including the WRX from 2002-2014 and the STI from 2004 onwards. It is also compatible with other Subaru models such as the Legacy GT (2005-2009) and Forester XT (2004-2008). Installation hardware and new gaskets are included, simplifying the upgrade process.
