Dinan 19-26 BMW 330i (G20)/21-26 BMW 430i (G22) Valved Axleback Exhaust System - Black Tips

Utilizing factory cut points and mounting mechanics the Dinan exhaust system is a straightforward install with precision fitment just like you would expect straight from the manufacturer. Mounting and proper fitment is where the similarities to the factory exhaust end, however. Fabricated from brushed 100% T304 stainless steel, TIG welded and free of hydroformed pipes the upgraded system is a substantial improvement from its predecessor - both in terms of material/construction as well as in overall looks. When viewed from the rear the difference becomes unmistakable if it was not already apparent. Going from the plebeian stock dual slash cut 90mm (3.5") tips to the massive Dinan straight cut 102mm (4") ones leaves no doubt that something above and beyond is present. This is solidified by the Dinan logo laser engraved on the tips and the deep growl of the exhaust that is indisputably different than anything one would expect to hear from a base 4-cylinder turbo platform. Stainless Steel - Black Tips - G20/G22 430i fitment is confirmed only for the coupe (G22) variant. The convertible (G23) and gran coupe (G26) have not been tested. They have additional underside bracing which may interfere with exhaust installation.

Upgrade the sound, appearance, and exhaust flow of your BMW with the Dinan D660-0091-BLK Valved Axle-Back Exhaust System. Designed for BMW 330i G20 sedan models from 2019 through 2022 and BMW 430i G22 coupe models from 2021 through 2022, this system uses factory cut points and mounting locations for a straightforward installation with precise, manufacturer-like fitment. Included mounting hardware helps simplify installation while retaining the vehicle’s factory valve control.
Constructed from brushed 100% T304 stainless steel, the Dinan exhaust is TIG welded and built without hydroformed piping for enhanced durability and a refined appearance. Larger-diameter piping improves exhaust flow, transitioning from 85mm inlet piping to dual 60mm outlets compared with the factory configuration. Drone-abatement technology helps reduce unwanted cabin resonance, while the upgraded system produces an enjoyably louder and sportier exhaust note suited to the BMW turbocharged four-cylinder platform.
At the rear, the system is finished with dual 4-inch double-walled, black ceramic-coated clamp-on exhaust tips. Each tip features a laser-engraved Dinan logo and a straight-cut design that provides a more substantial appearance than the factory tips. The system delivers maximum gains of up to 4 horsepower and 3 lb-ft of torque while providing a visual and auditory upgrade. Fitment for the 430i is confirmed only for the G22 coupe; G23 convertible and G26 Gran Coupe applications have not been tested and may have underside bracing that interferes with installation.
