HKS 08 Scion xB ES Wagon Muffler

The HKS 32019-BT001 muffler is constructed from SUS304 stainless steel, a material known for its strength and resistance to corrosion, which is important for exhaust components that face heat and moisture. This cat-back system is specifically designed for the 2008 Scion xB ES Wagon, aiming to improve exhaust flow and provide a more distinct sound compared to the factory setup.

This muffler features a 75mm (2.95 inch) diameter piping and a 120mm (4.72 inch) diameter muffler body, with a 102mm (4.06 inch) diameter exhaust tip. The larger pipe diameter helps reduce backpressure, allowing exhaust gases to exit more freely. This can lead to a more responsive feel from the engine, especially at higher RPMs. The design focuses on balancing performance gains with a sound that is noticeable but not overly aggressive, fitting for daily driving.

When installing this cat-back system, you'll be replacing the factory muffler and connecting pipe section. It's designed as a direct bolt-on replacement, meaning no welding or cutting is typically required, simplifying the installation process. Ensure you have the necessary tools and consider replacing any old or damaged exhaust hangers if they are worn, as this will help properly support the new system and prevent rattles.
