Constructed entirely from aerospace-grade titanium and topped with four carbon-fiber-sleeved tailpipes, the S-AU\/T\/2H adds 15 hp and 22 Nm of torque while cutting 14.3 kg of deadweight from the RS6's rear end. Akrapovic S-AU\/T\/2H retains full compatibility with the factory Audi exhaust valve system across Comfort, Dynamic, and Individual drive modes with no check engine lights or error codes. A required link pipe set (sold separately) connects the S-AU\/T\/2H to the factory catalyst section for a complete, race-grade installation. Every S-AU\/T\/2H system is TIG-welded and dyno-verified at Akrapovic's Slovenia facility.\u003c\/p\u003e\n\n\u003ch4\u003eKey
