ECS Tuning Centre X-Pipe Kit - Audi S5 3.0TFSI (B8 / B8.5)
Change the tone of your RS5 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 exponentially 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.
I have a B8.5 convertible RS5, with the factory sports exhaust which already provided an ok sound. After installing this - all i can say is WOW.
On comfort mode / valves closes sounds slightly louder than stock but
the car now totally opens up when you put it into sports mode and crackles nice and loud on downshift, much more of a redefined sporty sound. save money on full systems - get this its worth it 100% and not silly boy racer loud.
