SPD Performance SPD 2010-2021 Toyota 4.6L 5.7L Tundra High Flow Catted Stainless Downpipes TDP57T14SS

Performance Upgrade. The SPD Performance High Flow Catted Down-Pipes are engineered to enhance the exhaust flow of 4.6L and 5.7L Tundra engines from 2010 to 2021. This upgrade reduces back pressure, increases throttle response, and improves fuel economy, making it an essential component for drivers seeking enhanced engine performance while maintaining emissions compliance. Constructed from mandrel bent T304 stainless steel with a 3-inch diameter, these downpipes feature durable factory-style flanges and high-grade stainless clamps for a precise, leak-free fit. EPA approved catalytic converters made in the USA provide effective emissions control with racing-level capability, finished with a corrosion-resistant polished metallic look. Designed as a direct replacement for the factory Y-pipe, installation is straightforward and requires no custom tuning or modifications. The downpipes bolt directly onto existing exhaust components, simplifying the upgrade process for both professionals and enthusiasts. Specifically compatible with 2010 to 2021 Toyota Tundra models equipped with 4.6L or 5.7L engines. This product is not legal for sale or use in California and cannot be shipped there.
