Show original supplier description

The MAD Catless F10 M5 Downpipes represent a significant exhaust upgrade for BMW F10 M5 and F Chassis M6 models, aiming to enhance performance, sound, and aesthetics. They are engineered as a direct replacement for OEM downpipes, simplifying the installation process. By improving exhaust flow and eliminating restrictive factory catalytic converters, these catless downpipes reduce back pressure. This leads to measurable gains in horsepower and torque. Drivers can expect an increase of up to 30HP on a tuned BMW S63 with stock turbos, with even greater gains possible on vehicles equipped with upgraded turbos. In addition to performance benefits, the downpipes deliver a more aggressive and throaty exhaust note, designed with smooth bends to maximize airflow without introducing drone. Features include compatibility with both right-hand drive and left-hand drive vehicles, ensuring broad usability. MAD provides a lifetime warranty covering defects and fitment issues, along with a 90-day return period for customer satisfaction. All orders are processed for shipment within 1-2 business days. The listed fitment is for 2011+ F10 M5 and 2011+ F Chassis M6 models.
