Dinan Valved Axle-Back Exhaust with Polished Tips for G20 BMW 330i and G22 430i
The G20 330i Axle-Back Exhaust from Dinan is built for the B48 four-cylinder, adding real depth to a platform that’s often criticized for sounding thin from the factory. Dinan retains the factory exhaust valve, so the system stays civil in normal driving and opens to a deeper, fuller note free of added drone when you want it. Built from 100% T304 stainless steel, TIG-welded with no hydroformed pipe, it finishes in four polished stainless steel tips, double-walled with a laser-engraved Dinan logo on each. Dinan has built BMW performance parts since 1979, engineering this system to the same OEM+ fit and finish standard it applies across its lineup.
