Borla cat-back exhaust system.
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.
A cat-back system replaces everything behind the catalytic converter and leaves emissions equipment in place.
