Show original supplier description
The Turner Motorsport F3x 335/435i Valved Catback Exhaust system offers enhanced exhaust flow and a customizable sound experience for your BMW. Unlike many systems that use only one muffler exit for either open or closed valve operation, this Turner system utilizes both exits for both modes, providing a more refined and efficient performance. Constructed from beautiful 1.25mm thick, 80mm 304SS piping with smooth mandrel bends, this catback is designed for both aesthetic appeal and optimal exhaust gas flow. The kit includes a front exhaust section with a flex joint, a non-resonated mid-section, a high-flow valved axle-back muffler, a valve extension wiring harness, and a pair of 3.5" engraved Turner Motorsport exhaust tips. This valved catback exhaust system is specifically designed to fit the BMW F30 335i, F30 335i xDrive, F32 435i, and F32 435i xDrive models equipped with the N55 3.0L engine. Always use the vehicle selector to confirm precise fitment for your specific vehicle. The product is backed by a Lifetime Replacement Program, offering long-term peace of mind for your investment. Note that oversized and direct ship products may be excluded from free shipping offers.
