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

• Dual 4" (102mm) double-walled, polished clamp-on tips with laser engraved Dinan logo

• Drone abatement technologies used to reduce cabin resonance
• Factory-like fitment with included mounting hardware
• Maximum gains of +4 HP and +3 ft-lb of torque
• 100% 304 Stainless Steel construction
• Enjoyably louder, sportier sound
• Retains factory valve control

Upgrade your BMW with the Dinan D660-0091 valved axle-back exhaust system, engineered for factory-like fitment and a more engaging performance sound. Designed around the vehicle’s factory cut points and mounting locations, this system installs using included hardware for precise alignment and straightforward installation. It retains the factory valve control system while delivering an enjoyably louder, sportier exhaust note with a deeper growl than the original system.
Constructed from brushed 304 stainless steel, the Dinan exhaust is TIG welded for strength, durability, and a clean finished appearance. Larger-diameter piping improves exhaust flow, transitioning from the factory 85mm outlet to dual 60mm piping in the Dinan configuration. Drone-abatement technology helps reduce unwanted cabin resonance, allowing the system to provide an aggressive exterior sound without making extended drives unnecessarily intrusive.
The system is finished with dual 4-inch double-walled, straight-cut polished clamp-on tips featuring laser-engraved Dinan logos. Their larger appearance creates a noticeable visual upgrade over the factory dual 3.5-inch slash-cut tips. Maximum reported gains are up to 4 horsepower and 3 lb-ft of torque, while the valved design maintains compatibility with factory exhaust control operation. This application fits BMW 330i models using the G20 chassis from 2019 through 2022 and BMW 430i models using the G22 coupe chassis from 2021 through 2022. Dinan confirms 430i fitment only for the coupe; G23 convertible and G26 Gran Coupe models have not been tested and may have underside bracing that interferes with installation.
