Show original supplier description
The Turner Motorsport B48 Valved Axle-Back Exhaust is meticulously engineered to unlock the full potential of your 4-cylinder F chassis, offering an enhanced driving experience with improved performance and sound. In comfort modes, the valves remain closed, providing a refined exhaust note, while in sport modes, the valves open for a straighter flow path, unleashing a more aggressive, motorsport-inspired tone. Constructed from 1.25mm wall T304 stainless steel, this exhaust boasts superior durability and corrosion resistance. The design incorporates FARO ARM laser scanning and SolidWorks 3D CAD modeling for precision fitment, with T304 stainless steel hangers Tig-Welded in OE locations. Slip joints are utilized to provide maximum adjustability during installation. The kit includes the valved rear muffler, a valve extension harness, clamps, hardware, and dual 3.0" exhaust tips. This axle-back exhaust is specifically designed for various BMW F30, F31, F32, F33, and F36 models equipped with the B48 or B46 2.0L 4-cylinder engine. Please use the vehicle selector to confirm exact fitment for your specific model.
