Milltek Sport BMW M340i Touring (F31) Cat-Back Exhaust System Elevate your M340i Touring's performance with this precision-engineered cat-back exhaust from Milltek Sport. Built from premium stainless steel, the system combines durability with a refined aesthetic, resisting corrosion whilst maintaining its finish over years of use. The optimized internal geometry reduces back pressure significantly, enabling your 3.0L turbo engine to expel gases more efficiently and unlock additional horsepower and torque across the rev range. Beyond raw performance gains, you'll experience a distinctly more aggressive exhaust character—deeper and more purposeful than stock—that reflects the true capability of your M340i. The engineering prioritizes both responsiveness and refinement, delivering noticeable throttle response improvements without excessive drone at cruising speeds. Installation is straightforward thanks to the direct-fit design, which integrates seamlessly with your existing OEM components and mounting points. No modifications or additional fabrication required. Engineered specifically for the F31 Touring (2018-2019 models), this exhaust system represents a genuine upgrade for drivers seeking measurable performance enhancement combined with auditory satisfaction.
