Borla 05-08 Subaru Legacy GT Cat-Back System

Borla is known for performance exhaust systems, and this S-Type cat-back system is built specifically for your 2005-2009 Subaru Legacy GT 2.5L Turbo. If you're looking to give your turbocharged Subaru a more aggressive sound and potentially unlock some extra power, this system is designed to do just that. It replaces the factory exhaust from the catalytic converter back, featuring Borla's signature straight-through, free-breathing mufflers.

This system is constructed from aircraft-grade T-304 austenitic stainless steel, which is a strong material that resists corrosion, especially important with the high temperatures from a turbocharged engine. The pipes are CNC mandrel bent for smooth airflow, with a 2.5-inch diameter feeding into a dual 2-inch split rear configuration. You'll get Borla's classic S-Type sound, which is described as powerful without causing interior drone, and the exhaust exits through polished 4.25-inch x 3.5-inch oval T-304 stainless steel tips with rolled edges. Borla's testing indicates power increases due to the improved airflow, and the entire system is about 20% lighter than the stock setup.

Installation is designed to be a bolt-on affair, meaning you won't need welding or extensive modifications. The system comes with Borla's million-mile warranty, offering peace of mind for this significant upgrade to your Legacy GT.
