ECS Tuning Audi B8/B8.5 S4/S5 3.0T Downpipes For Factory Cat Back Exhaust

Change the tone of your B8 S4/S5 3.0T with easy-to-install downpipes and an integrated X-pipe, designed to fit seamlessly with your factory cat-back exhaust. These ECS Tuning downpipes bolt-up to your factory cats and then reduce down to an x-pipe to increase tone and allow for better flow of exhaust gases.

The engineers at ECS Tuning have designed direct-fit dual downpipes featuring an X cross-section in the center to balance exhaust pulses and increase the expulsion of spent exhaust gases from the engine. But more importantly, the installation of these downpipes increases the factory exhaust system note exponentially, giving a more tuned European sound. The ECS downpipes are mandrel bent from high-quality 304 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 installation 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.
