Dinan Engineering has designed a new complete exhaust system for the BMW M340i, the most capable latest-gen 3 Series to date. Hit play and turn up the volume!
The entire system is made of stainless steel pipes measuring 76 mm (3 inches) across, making it wider than the stock 70 mm (2.73”). It also weighs in at 4 lbs (1.8 kilos) under the stock one. The four tips can be ordered in Ceramic Black and Polished finishes. The shop claims you get up to 6 horsepower (4.5 kW) and 7 Nm (5 lb-ft) of torque from the upgrade, attainable around 6,600 RPM.
What is also nice, you can adjust the timbre on the go by means of a handy remote control.
