New Audi 8V RS3 ECS Valved & Race Exhaust Systems

The DAZA-equipped RS3 is undoubtedly considered to be legendary amongst automotive enthusiasts. The leading reason for this status is an exhaust note unlike anything else on the road. This 2.5L turbocharged 5-cylinder monster delivers a remarkable, deep and aggressive tone that can only be described as complete auditory perfection. At ECS, we've set out to perfect the renowned DAZA note with a gorgeous stainless steel cat-back exhaust that retains factory valve functionality the perfect system combination for each and every enthusiast. OR go full race mode and get the Race Catback for the increase in flow from dual 2.75" (70mm) 304 stainless steel exhaust pipes that feed into a 3.5 (89mm) collector pipe into the straight-through free flowing rear section.
