Borla 140121 Mazda3 Catback Exhaust
BORLA® engineers developed an awesome 2.5" diameter performance Cat-Back™ system for the Mazda 3. Many were nervous when Mazda elected to replace the popular Protégé with the Mazda 3, but the resulting vehicle was a homerun. The '04-'09 Mazda 3 is a great 4-door with an excellent power package in the 2.3L 160 horsepower engine and performance handling suspension straight off of the Mazda 6.
The system has a super look, sound and performance. Designed to work with both automatic and stick shift transmissions, this performance exhaust upgrade is lighter than stock and has 14% better air flow which generates solid performance gains through the entire dyno RPM graph. The system features the classic S-Type sound with no drone inside the vehicle, and a 4" round polished T-304 stainless steel tip.
BORLA®, the original pioneers of aerospace-grade high quality T-304 austenitic stainless steel (superior to 409 or aluminized steel) free-flow exhaust utilizes patented award and race winning technology to deliver quality, sound, performance gains and enhanced fuel economy — all with an easy bolt-on installation and backed by an unsurpassed written Million-Mile Warranty.
