ECS Tuning B8 S4/S5/Q5 3.0T Downpipes w/ Resonator Deletes

Change the tone of your B8 S4/S5 3.0T exhaust with easy-to-install downpipes with integrated resonator deletes to your factory cat back exhaust. The ECS Tuning downpipe kit installs to your factory cats and deletes the large factory resonators fitting up to your factory exhaust to increase exhaust note and allow for less restricted flow of exhaust gases.

The engineers at ECS Tuning have designed a direct fit dual downpipes featuring a straight mid section in the center to delete the factory resonators and increase expulsion of spent exhaust gases from the engine. But more importantly, 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 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.
