Borla cat-back exhaust system.

The BORLA Team has an awesome sounding exhaust for your Sonata. The S-Type system delivers a sound that is much sportier than stock, yet far from obnoxious, and is drone-free. System includes a flow plate to eliminate check engine light that may be caused by the increase of airflow of the BORLA system. The muffler features BORLA's Polyphonic Exhaust Harmonizer technology which utilizes patented units that contain pipes of different diameters and lengths to create multiple exhaust notes that harmonize to deliver a clean, rich, full bodied sound. BORLA Cat-Back™ & Axle-Back exhaust systems feature patented straight-through and multi-core technology to unleash hidden horsepower. Increased exhaust velocity adds power, driving excitement, fuel economy, and the distinctive BORLA Sound of Power respected by motoring enthusiasts everywhere. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit. Just what you'd expect from the world's most experienced (and most winning) exhaust brand. Bolt-on a BORLA and get the sound to match your Hyundai's Performance.

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