3-Inch High-Flow Downpipe Exhaust

The SPELAB 3-inch High Flow Downpipe is engineered as a direct replacement for the factory downpipe on 1999-2006 Audi S3 and TT models equipped with the 1.8T engine. By removing restrictive stock components, this downpipe facilitates smoother exhaust gas exit from the turbocharger, resulting in significant gains in horsepower and torque for turbocharged vehicles. Constructed from premium 16-gauge T-304 stainless steel, the downpipe features computer-aided mandrel-bends for optimal flow and TIG-welded joints to ensure robust construction and prevent cracking. The CNC-machined flange provides maximum strength and durability, while the chrome-plated flange offers enhanced corrosion resistance. The mirror polish surface finish adds to its aesthetic appeal. Its large diameter and free-flow tubing are intended for unrestricted exhaust flow, making the exhaust air flow smooth. The product is ISO9001:2000 certified, underscoring its quality standards. **Fitment:** * 1999-2006 Audi S3 1.8T * 1999-2006 Audi TT 1.8T
