BORLA 140312 Cat Back Exhaust System IMP WRX STI 08- 09 2.5L

Description BORLA 140312 Cat Back Exhaust System IMP WRX STI 08- 09 2.5L

BORLA Performance offers a quad-exit Cat-Back exhaust system for the 2008–2014 Subaru WRX STi. This race-inspired system (PN140312) is designed to enhance the performance of the flagship model.

The exhaust plumbing has been upgraded from 2.5" to 3" in diameter, resulting in increased airflow and horsepower gains of 7% to 10%. The system muffler is positioned higher than the original equipment, providing a 1.75" clearance gain, which improves both aerodynamics and appearance by reducing clutter at the back of the vehicle.

The system is lighter due to BORLA's patented straight-through design, eliminating baffles and chambers and reducing weight by approximately 8 lbs. The exhaust amplifies the STi's distinctive sound with a rich bass tone, and features high-quality austenitic stainless steel construction with 3.5" double-walled rolled-edge polished T-304 stainless steel tips. Installation is bolt-on, and the system is covered by a Million-Mile Warranty for street applications.
