ECS Tuning Center X-Pipe Kit - C7 S6/S7/RS7 4.0T

Change the tone of your Audi S6/S7 4.0T exhaust with an easy-to-install upgrade from ECS Tuning! The ECS Tuning Center X-Pipe installs in place of the resonator located in the middle of the factory exhaust system to increase exhaust note and allow for better flow of exhaust gases.

The engineers at ECS Tuning have designed a direct fit dual exhaust pipe featuring an X cross section in the center to balance exhaust pulses and increase expulsion of spent exhaust gases from the engine. But more importantly, installation of the Center X-Pipe increases the factory exhaust system note releasing a sophisticated European V8 growl. The ECS X-pipe is fully CNC mandrel bent from high quality 304L stainless steel, tig welded with smooth merged pipe joints for optimal flow, and finished off with a soft brushed finish for exceptional looks. Installation is a breeze and can be easily performed with the vehicle lifted on proper jack stands in your own driveway. Our in-depth installation PDF, located under the Installation Tab, walks you through everything from proper measurement, cutting, and install to ensure a perfect fit to your OEM exhaust. We've even included a complete set of clamps to make sure everything is properly installed without worry of leaks.
