Midpipe SS304 Stainless Steel

The ARM Motorsports B58MID3 is a performance midpipe engineered to amplify the aggressive exhaust note of B58-powered BMWs while retaining the OEM muffler for volume control. This SS304 stainless steel upgrade replaces the stock vehicle's two central resonators, offering a lighter weight and improved sound profile. The midpipe features smooth, mandrel-bent tubing with a 3.25” diameter throughout its full length, connecting via a slip-fit design with included performance-grade exhaust clamps. This midpipe is designed for BMW models including the F30 340i, 340i xDrive, F32 440i, 440i xDrive, F34 340i Gran Turismo, 340i Gran Turismo xDrive, F36 440i Gran Coupe, and 440i Gran Coupe xDrive, all equipped with the B58 3.0L engine. The product comes with two ARM B58 Midpipe Sections and four exhaust clamps. It is important to note that this product is intended for Off-Road Use Only.
