Borla Cat-Back Exhaust - Ford Focus RS (LZ) - ATAK Split Rear Exit
This Borla cat-back exhaust suits the Ford Focus RS (LZ) and replaces the factory system from the catalytic converter back. It exits through single split rear tips and uses Polyphonic Harmonizer technology with ATAK mufflers for Borla's most aggressive sound, tuned to avoid drone in the cabin. A valve simulator replaces the factory sound valve for full flow at all times.
Note: Includes a valve simulator that eliminates the factory sound-suppressing valve without dashboard warning lights. Care tip: stainless steel polish is not recommended on the black chrome tips. Designed around the US-market vehicle; the rear exhaust layout is shared with Australian right-hand-drive cars, but please confirm fitment with our team before ordering, including any Australian-spec emissions hardware (such as a particulate filter) and rear bumper or valance differences. Installation by a professional is recommended.
