The AWE Tuning Touring Edition cat-back exhaust replaces the factory system with a full 3 in (76mm) mandrel-bent T304L stainless steel design that flows roughly 65% more than stock and adds up to 10 horsepower and 17 lb-ft of torque at the wheels on stock software. AWE's patented 180 Technology cancels interior drone so the M240i stays composed at highway cruise, then delivers a fuller B58 tone under throttle. It is a direct bolt-on cat-back requiring no cutting and retains factory-style exhaust tips.
