ATEXHBMW1 AIRTEC MOTORSPORT DE-CAT DOWNPIPE FOR BMW B58 ENGINE

The AIRTEC Motorsport De-Cat Downpipe is designed to replace the restrictive factory catalytic converter, reducing back pressure and improving engine performance. With less restriction, you'll experience quicker throttle response, a noticeable increase in power, and a more aggressive exhaust sound.

Supplied with an adaptor to connect seamlessly to the stock exhaust system, the downpipe also fits aftermarket systems, making it a versatile upgrade for both OEM and modified setups.

Additionally, AIRTEC Motorsport is one of the few manufacturers offering a cast elbow design, preserving the diameter for optimal flow and performance.

Features:

• Constructed from high-quality stainless steel
• AIRTEC laser-etched logo for authenticity
• Smooth, mandrel-bent pipes to maximize flow and performance
• Compatible with both OEM and aftermarket exhaust systems
• Performance gains further enhanced with an ECU remap
