This catback hits everything you’re looking for when it comes to an exhaust system. It sounds aggressive when it’s “race car” time with the exhaust valve open, but retains factory convenience and noise reduction when you need it by closing the valve. You’ll also get increased flow that is ready to handle big increases in power, which provides big performance potential along with a fantastic sound.

This 3” Stainless Steel Dual Tip Cat-Back is a direct replacement exhaust that boasts complete 304 stainless steel construction, custom inline straight through resonator plus muffler and dual polished 4.5” double-wall slash cut tips. COBB’s exhaust also features the same OEM exhaust valve found in your factory cat-back, so there is no need to remove and transfer the original unit. The exhaust valve is a direct plug and play connection that is controlled by the in car drive modes and works perfectly with COBB’s OTS maps or a custom Pro-Tune (not included).

Tech Tip: Your RS’s factory/OEM exhaust system has to be cut in order to be removed.
