Change the tone of your B9 S4 3.0T 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. Weighing in at 11.7 pounds, our X-Pipe also shaves off 4.6 pounds from the OEM center resonator!
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 note giving a more tuned European sound. 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.
Does not include ECS Tunnel Brace shown in photograph.
Installation requires cutting of the OEM exhaust using an exhaust pipe cutter, reciprocating saw, or other similar tool. Installation services are available at our facility in Newmarket, ON. Installation guide can be found here for DIY'ers!
