SPDZ1 Carbon Fiber Axle-Back Muffler Exhaust – BMW F30 335i / F32 435i (2012–2016)
Enhance the performance, sound, and appearance of your turbocharged BMW with the SPDZ1 Carbon Fiber Axle-Back Muffler Exhaust, engineered for the F30 335i and F32 435i platforms. Designed to reduce restriction and weight while delivering a sharper, more aggressive exhaust note, this axle-back system offers a true performance upgrade with a premium motorsport look.
Constructed from high-quality stainless steel piping and finished with real dry carbon fiber exhaust tips, this system dramatically improves exhaust flow and frees up the breathing capability of BMW’s 3.0L turbocharged inline-six. The result is improved throttle response, a deeper exhaust tone, and substantial weight savings compared to the factory muffler assembly.
The carbon tips are secured using a 6-point mounting system, ensuring long-term stability and precise alignment under aggressive driving conditions.
