aFe Catback Exhaust for BMW 07-13 328i (E92/93) w/ polished tips

Introducing the new aFe Power MACH Force XP cat back exhaust system for the 07-13 BMW 328i E92 & E93 non-turbo. In recent testing, this system produced 4 horsepower and 8 lbs. x ft. of torque. This exhaust is constructed from 2.5" brushed finish, mandrel bent, 304 stainless steel and is TIG-welded. A high flow, 304 stainless steel, single in dual out muffler was used to maximize performance across the power band while maintaining a great tone. To finish off this exhaust are dual, aFe laser etched, 3" polished 304 stainless steel tips. This exhaust uses all factory hanger locations. Note: Cutting is required and should be performed by a skilled technician. . Retains Rear Catalytic Converters:The rear cats are retained on this system to maintain a smooth, deep sound but more importantly to keep the system street legal. Mitered Merge Collector:Mitered collectors decrease turbulence and increase exhaust velocity resulting in increased horsepower, torque and improved throttle response.L
