Product Description

The Borla 140509 S-Type Cat-Back Exhaust System is a premium performance exhaust engineered specifically for the 2012-2016 BMW 328i Sedan (F30) and 428i Coupe (F32) equipped with the N20 2.0L turbocharged four-cylinder engine. Designed to replace the restrictive factory system, this Cat-Back boosts exhaust flow, enhances throttle response, and provides a more engaging driving experience with Borla's signature aggressive, yet refined, "Sound of Power."

Constructed entirely from T-304 stainless steel with smooth mandrel-bent tubing and precision CNC components, the 140509 delivers long-lasting corrosion resistance and a perfect fit. Its straight-through, multi-core muffler design increases exhaust velocity while keeping interior drone low, making it ideal for daily driving and spirited performance use. The system includes polished dual round rolled angle-cut tips that complement the BMW's rear styling. Please note this system is engineered for the N20 2.0T engine and does not fit the N26 SULEV variant. Backed by Borla's Million-Mile Warranty, this Cat-Back exhaust is a top choice for enthusiasts seeking performance gains and an aggressive exhaust note.
