Product Info

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!

Designed using the latest in CAD technology; this part is made to fit perfectly in place of restrictive factory catalytic converter. Manufactured from T304 stainless steel, hand TIG welded and back-purged to ensure years of reliable performance.

In 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.
