Dinan Valved Axle-Back Exhaust with Black Tips for BMW M240i G42 (2022-2026)

D660-0098-BLK puts four black ceramic-coated tips on Dinan's valved axle-back for the G42 M240i. The 4-inch (102 mm) straight-cut, double-walled outlets carry a laser-engraved Dinan logo and suit Shadowline trim and darker paint. The rest matches the polished kit: brushed T304 stainless tubing that grows from 70 mm to 76 mm, a measured plus 6 horsepower and plus 5 lb-ft at 6600 rpm, and about 4 pounds less weight than the factory system.

The stock exhaust uses a single valve that closes off one side. Dinan keeps the original actuator and adds a matching valve on the other side for symmetrical flow and sound. Each valve is 76 mm, roughly 30 percent less restrictive than BMW's. With them open, the outer pipes deliver a deep, near straight-through tone. With them closed, the muffler handles all the flow and the inner tips stay quiet for town driving. Dinan's drone-abatement design keeps conversation easy at cruising speed.

Dinan's title for this finish is 2022-2026 BMW M240i. U.S. sales began with the 2022 M240i xDrive Coupe, and the rear-drive M240i followed for 2023; the table uses those first years and runs through 2026. The system bolts in with factory-style mounting and supplied hardware, and Dinan lists 2.5 hours of labor. The 230i, G87 M2, and older F22 M240i use different exhausts. The polished-tip sibling is D660-0098.

Emission code 5 applies; 3 Dinan points. The boxed kit ships at 51.6 x 26.4 x 12 inches and 72 pounds. Dinan's limited warranty runs for the remainder of the vehicle factory limited warranty (up to 4 years / 50,000 miles) or 2 years / unlimited miles, whichever is greater. The DNN-prefixed duplicate listing now redirects to this page.
