CTS Turbo 2018+ B9 Audi S4/S5 V6T 3.0T (EA839) HIGH-FLOW CAT
CTS Turbo B9 S4/S5 3.0T (EA839) high flow cat is made to maximize exhaust flow for highest power gains. Do not compromise performance and sound with factory parts - unleash your B9 S4/S5 3.0T potential! \n \nDesigned using the latest in CAD technology; this part is made to fit perfectly in place of restrictive factory catalytic converter. Manufactured from cast T304 stainless steel, hand TIG welded and back-purged to ensure years of reliable performance. \n \nIn addition to unleashing the power and performance of your 3.0T, the CTS B9 S4/S5 3.0T EA839 high flow cat will make your vehicle sound like an S-car really should. When installed with factory exhaust it produces a sporty growl with much more pronounced exhaust "crackle" on downshift. While up-shifting you will enjoy a confident "braappp!" as you bang through all 8 gears. The sound will be even louder if you already have an aftermarket exhaust system. \n \nProduct Details: \n
