Show original supplier description

The X-Force Pro Series Catted Downpipe is a high-performance exhaust upgrade designed for Subaru WRX and STI models from 2008 onwards. Constructed from durable 304 stainless steel, this downpipe features robust 3-inch pipe work and a cast stainless steel upper section to optimize exhaust flow. The mandrel bend construction ensures smooth transitions and maximum efficiency. This downpipe is equipped with a 100-cell metallic high-flow catalytic converter, designed to enhance exhaust gas flow while maintaining emissions compliance. The brushed finish provides a clean, performance-oriented aesthetic. It is important to note that this downpipe features a bell-mouth style and a 100-cell metallic high-flow cat converter. It does not fit the OEM cat-back exhaust system.
