Dinan’s new tuned, bolt-on exhaust system for the 2014-2018 BMW 4 Series powered by the B58 3.0L turbocharged inline-6 engine adds dyno-proven power and a sporty sound
Opelika, Ala. (July, 2018) – BMW specialist Dinan Engineering has launched a complete, bolt-on exhaust solution to bring a more aggressive sound to the convertible and Gran Coupe versions of the 2014-2018 turbocharged 4 Series. Dinan engineers designed the F33 and F36 440i exhaust to improve exhaust flow and reduce back pressure, resulting in increased power output and a sportier sound.
Dinan’s new bolt-on Free Flow exhaust system for the F33 and F36 440i was designed to add a more aggressive sound under acceleration and more horsepower while reducing drone inside the vehicle thanks to the incorporation of a Helmholtz chamber in the muffler. The Free Flow Exhaust system also eliminates the factory computer-controlled exhaust valve and delivers gains of 6 horsepower and 5 pound-feet of torque while remaining 50-state emissions compliant.
This new exhaust system features mandrel bent 16-gauge 304 stainless steel piping for superior corrosion resistance and was measured to exacting specifications to ensure proper fit. The exhaust gasses exit out of laser-engraved twin 89mm ceramic black or polished stainless-steel exhaust tips and the system was designed to fit with both the factory bumper and M-sport optioned vehicles.
Every Dinan product comes with its factory-matching new car warranty and was designed and tested in Opelika, Alabama. Dinan products can be purchased and installed at any Dinan Approved BMW dealership nationwide. For more information on Dinan products and signature vehicles, visit www.dinancars.com.
