CTS Turbo Audi 8V S3 3" Turbo Back Exhaust High-Flow Cat

This CTS Turbo turbo back exhaust system replaces the factory setup on 2015-2020 Audi 8V S3 models with a full 3-inch mandrel-bent design. The integrated high-flow catalytic converter maintains emissions compliance while significantly reducing backpressure compared to the restrictive OEM arrangement. Engineered for workshops tuning EA888 Gen 3 platforms, this system provides improved exhaust velocity and scavenging to support higher output calibrations. Precision TIG-welded construction ensures durability under sustained performance use, with proper fitment that doesn't compromise ground clearance or require cutting.
