For the ultimate in weight reduction, tuning potential, and racing sound, Akrapovi_ offers stainless steel, cat-less downpipes to make the Audi an even more powerful machine. This setup is intended for dedicated track-day cars and enthusiasts, and it will also add to the overall experience of whatÕs already a stunning performance car for any discerning driver. Delivering great sound, without creating unwanted cabin noise, these beautifully-crafted downpipes offer an upgrade to Akrapovi_Õs Evolution exhaust system. Downpipes must be combined with one of the front link pipe set. Choose L-AU/SS/3 if the car is equiped with Akrapovi_ aftermarket evolution line exhaust system or L-AU/SS/4 if it is fitted with Akrapovi_ exhaust system developed for Audi Sport (Audi product code for S6/S7 - 4G0071897, for RS6 /RS7 - 4G0089253A00). When installing Akrapovi_ aftermarket optional down pipes with sports catalytic converters or without catalytic converters, which are developed for use on closed tracks only, remapping the ECU is mandatory. When installing Akrapovi_ aftermarket exhaust system that was developed for use on closed tracks, we recommend remapping the ECU in order to prevent potential Ècheck engine lightÇ warning signals. THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.
