Description

The Cobb Tuning Cat-back Exhaust is engineered for the BMW 3-Series, offering a blend of OEM fitment, innovative design, and superior craftsmanship. Constructed from durable 2.5" and 3" 304 stainless steel, this system features CNC mandrel-bent tubing with precise TIG welds for optimal flow and longevity. A strategically placed Helmholtz chamber is incorporated to effectively reduce exhaust resonance, ensuring a refined sound. Installation is streamlined with V-band clamp connections, allowing for infinite adjustability and a secure fit. The system is completed with 4" slip-fit exhaust tips, providing flexibility in adjusting tip placement for a personalized aesthetic. Applications include the 2007-2013 BMW 335 models. However, it is important to note that this exhaust system does not fit convertible models. Installation requires custom tuning or utilizing an appropriate COBB Stage Power Package map for optimal performance. Necessary hardware is included in the box.
