Description
The CarBahn Performance Stainless Steel Exhaust System is a full cat-back exhaust upgrade designed for BMW M340i and M440i models equipped with the B58 engine. Constructed from high-quality 304 stainless steel, this system delivers a deeper, more aggressive exhaust tone while maintaining a refined sound during highway cruising.
Designed for enthusiasts who want a more engaging exhaust note without excessive cabin drone, the CarBahn cat-back system retains the factory electronic valve control. This allows the exhaust character to remain controlled during normal driving while providing a more aggressive sound under throttle.
The complete cat-back design replaces the exhaust system from the catalytic converter back, providing an upgraded exhaust flow path and enhanced sound while maintaining the functionality of the factory electronic exhaust valves.
