Overview

The Brandless HS08SW1DPN is a catless downpipe designed for Subaru WRX and STI models. It features an open bellmouth design to improve exhaust flow from the turbocharger. This downpipe is constructed from 304 stainless steel for durability and high-temperature resistance, with a laser-cut cast steel flange for a reliable seal.
Show original supplier description
The Brandless HS08SW1DPN is a catless downpipe designed to optimize exhaust flow for Subaru WRX 08-14, STI 08-21, Liberty 07-09, and FXT SH models with 5MT, 6MT, or 4AT transmissions. It features an open bellmouth design that significantly reduces exhaust restrictions and turbulence as gases exit the turbocharger. This design, combined with a larger pipe diameter and smooth bends, allows the turbo to expel exhaust gases more freely. Constructed from 304 stainless steel for the bellmouth and piping, this downpipe is built to withstand the high temperatures encountered near the turbocharger. The flange is made from cast 304 stainless steel, laser cut for a precise fit, ensuring long-lasting, leak-free reliability. This component is designed as a 100% bolt-on installation for Australian specification, right-hand drive vehicles, requiring no modifications or changes to the steering knuckle. Factory O2 sensor locations are maintained for compatibility with existing systems.
