Description
Maximize the performance of your B9 Audi S4/S5 3.0T (EA839) with the CTS Turbo High-Flow Cat. Engineered for optimal exhaust flow, this high-flow cat unlocks the true potential of your vehicle, delivering substantial power gains and an enhanced exhaust note. Designed with advanced CAD technology, it fits seamlessly in place of the restrictive factory catalytic converter.
Crafted from cast T304 stainless steel, each high-flow cat is hand TIG welded and back-purged for durability and reliability. Experience the full power of your 3.0T engine while enjoying a sporty growl and pronounced exhaust crackle on downshifts. The sound is further amplified if you have an aftermarket exhaust system, yet remains drone-free with the factory exhaust.
