Show original supplier description
The CVF 3" Stainless Steel Catted Downpipe is engineered as a direct bolt-on replacement for the 2015-2023 Ford Mustang equipped with the 2.3L EcoBoost engine. Constructed from durable T304 stainless steel, this downpipe features a 3-inch diameter and incorporates a 200-cell high-flow catalytic converter. The primary benefits of this downpipe include increased power output and a more aggressive exhaust sound. Its T304 stainless steel construction ensures longevity and resistance to corrosion. The 100% mandrel-bent tubing maintains consistent diameter for optimal exhaust flow. Installation is described as plug-and-play, with users reporting that the build quality and fitment exceed expectations. The downpipe is compatible with both OEM and aftermarket exhaust systems. While it offers improved performance, some users suggest considering a tune for optimal results and to prevent a rich running condition, though the product page does not explicitly state this requirement. The product comes with a lifetime warranty, underscoring the manufacturer's confidence in its quality and durability.
