HKS 2008 STi 65mm Stainless Steel Mid-Pipe (only compatible w/ hks31021-AF012 or Stock Muffler)

This HKS 65mm stainless steel mid-pipe is made specifically for the 2008 Subaru Impreza WRX STI. It's designed to connect to either the HKS 31021-AF012 exhaust system or your car's original stock muffler, giving you some flexibility in how you build out your exhaust setup. If you're looking to replace a damaged or rusted mid-pipe, or if you're starting a custom exhaust project on your STI, this part from HKS offers a well-built foundation.

Constructed from durable stainless steel, this mid-pipe is built to handle the heat and corrosive elements that exhaust systems are exposed to. The 65mm diameter is a specific size that HKS has chosen to work with their other components or the factory muffler, aiming for a balanced performance improvement without being overly aggressive. While it's not CARB approved and cannot be shipped to California, for other regions, it represents a solid option for STI owners wanting to maintain or upgrade their exhaust system with a reputable brand.

When installing this mid-pipe, ensure you have the correct gaskets and hardware. It's designed as a direct replacement for the factory mid-pipe connection point, but always refer to the manufacturer's installation instructions for the most accurate guidance. This part is intended for use with specific HKS components or the stock muffler, so double-check your existing setup to ensure compatibility before purchase.
