Catback Exhaust System

The Integrated Engineering Catback Exhaust System is engineered for the Audi B9 A4 2.0T, delivering an aggressive yet refined exhaust note without the rasp often found in downpipe-only setups. This system utilizes Integrated Engineering's proprietary DroneTrap technology to actively cancel out irritating drone sound waves, ensuring a more enjoyable auditory experience. The large, 90mm slash-cut exhaust tips feature a motorsport-inspired brushed finish and are adjustable for depth, allowing for a personalized aggressive aesthetic. Constructed from corrosion-resistant T304L stainless steel, this catback exhaust boasts a high-flow design with 2.5-inch CNC mandrel-bent piping. It features strong, multi-point, boxed exhaust hangers for enhanced durability and longevity, along with reinforced bridged sections to prevent rattles. The system is designed for a straightforward, DIY-friendly installation, requiring no cutting or welding, with an average installation time of one hour and includes hardware for both stock and iE downpipes (PN: IEEXCK9). Compatibility is specific to the Audi B9 A4 models from 2017-2019 equipped with the 2.0T engine. It is designed as a direct fit with either the stock downpipe or the iE ProCore Downpipe (PN: IEEXCK9). For builds utilizing an iE v-band style downpipe (PN: IEEXCK1), customers are advised to contact Integrated Engineering after purchase for specific installation details.
