X-Clear Driveshaft Tunnel Brace, B8 Audi A4/S4/RS4 & A5/S5/RS5

The X-Clear Driveshaft Tunnel Brace is designed to increase clearance for aftermarket exhausts by replacing the shallow-fitting OEM tunnel brace. This allows for a larger diameter exhaust to be installed without causing excessive rattling or vibration, while also utilizing an integrated aeroflap to maintain OE underbody aerodynamics.
The X-Clear Driveshaft Tunnel Brace replaces the factory brace with a CNC Machined Billet 6061-T6 Aluminum brace designed to increase exhaust clearance by 5mm over factory.

NVH is the measurement of how much noise, vibration, & harshness gets transmitted into the cabin of your vehicle. Based on user feedback, 034Motorsport X-Clear Tunnel Braces transfer zero amounts of NVH to the cabin. NVH is subjective, so some users may find NVH to be increased or decreased from our rating. If you are experiencing higher than quoted NVH with this product, please evaluate the installation to ensure to components are correctly installed and email techsupport@034motorsport.com for further assistance.
