Dinan Valved Axle-Back Exhaust with Polished Tips for G80 BMW M3 and G82 / G83 M4

Dinan G80 M3 polished exhaust is a T304 stainless steel valved system for the G80 BMW M3, G82 M4, and G83 M4 Convertible and their S58 twin-turbo inline-six. Stock exhaust valve actuators are reused, so exhaust tone still adjusts through the factory M-Drive settings exactly as before, while the system reduces backpressure for a louder, fuller note than the muted factory setup. Finished with four diffuser-filling 4.5-inch polished stainless clamp-on tips, TIG-welded and brush-finished throughout, it comes in 6lbs lighter than stock.

Frequently Asked Questions

What does the Dinan G80 M3 polished exhaust fit? The Dinan G80 M3 polished exhaust fits the G80 BMW M3, G82 M4, and G83 M4 Convertible (2021-present) with the S58 twin-turbo inline-six. It bolts to the factory mounting points, replacing the rear section of the exhaust for a louder, fuller note.
Does the Dinan G80 M3 polished exhaust still work with the M-Drive valve control? Yes. Stock exhaust valve actuators are reused, so the exhaust tone still adjusts through the factory M-Drive settings exactly as it did before. The computer-controlled valves stay quiet at low speed and open fully under high load.
What finish are the tips on the Dinan G80 M3 polished exhaust? This version uses four diffuser-filling 4.5″ (114mm) polished stainless clamp-on tips. A black ceramic finish is offered separately as Dinan part number D660-0093-BLK. The system is 100% T304 stainless steel, TIG-welded and brush-finished.

About Dinan

Founded in 1979, Dinan is North America’s leading BMW tuner, developing, manufacturing, and marketing a full line of high-performance products for BMW, MINI, and Mercedes-Benz. Dinan works through a nationwide network of Authorized Dinan Performance Centers, including select BMW dealerships and independent BMW service and performance shops.

Every Authorized Dinan Performance Center can help build anything from a single upgrade to a complete Dinan BMW.
