Overview

The Turner Motorsport Catback Valved Exhaust is a performance exhaust system designed for the E9X 335i N54/N55 models. It features mandrel-bent dual 2.5-inch 304SS pipes with a brushed finish and Turner-engraved polished exhaust tips. The system includes high-flow, vacuum-controlled valved mufflers that remain quiet during normal driving but open up to provide a menacing growl under throttle.
Show original supplier description
The Turner Motorsport Catback Valved Exhaust is engineered for the E9X 335i N54/N55 models, aiming to enhance the driving experience with improved exhaust notes and a noticeable performance increase. This system is constructed from mandrel-bent dual 2.5-inch 304SS pipes, featuring a brushed finish and polished, Turner-engraved exhaust tips. Accuseal slip-fit joints are incorporated for straightforward installation, utilizing factory exhaust hangers for a direct bolt-on replacement of the OE system. This exhaust system offers a dual-purpose capability. Under normal driving conditions, the vacuum-controlled muffler valves remain closed, maintaining a discreet sound profile that closely resembles the factory exhaust. However, when the throttle is opened, these valves engage, unleashing a powerful and aggressive growl. The system is available in axle-back, cat-back, and full turbo-back configurations. Important restrictions apply to this product. It is not for sale or use in the state of California on any pollution-controlled vehicle, as per the California Air Resources Board regulations.
