Show original supplier description
The CTS Turbo B9 S4/S5 3.0T (EA839) high flow cat pipe is engineered to replace the restrictive factory catalytic converter, significantly improving exhaust flow to achieve maximum power gains. This component is precision-crafted from premium T304 stainless steel, featuring hand TIG welded and back-purged construction to ensure exceptional durability and years of reliable performance. Designed using advanced CAD technology, it ensures a perfect fit, seamlessly integrating with your vehicle's existing exhaust system. Beyond performance enhancements, the CTS Turbo high flow cat pipe transforms your Audi's exhaust note into a sporty growl, adding a more pronounced "crackle" on downshifts and an aggressive "braappp" during upshifts, especially when paired with an aftermarket exhaust system. It offers a great power upgrade with uncompromising performance and a stunning polished finish. Please Note: To prevent a Check Engine Light (CEL) from appearing after installation, proper tuning software must be used. Installation hardware is included.
