Alpha Series 3-Inch Race Downpipe

The Skunk2 Racing Alpha Series Race Downpipe is engineered to enhance exhaust flow and performance in the 2018-2021 Honda Civic Type R models, including the Limited Edition Hatchback. Built with decades of race engineering experience, this downpipe utilizes a large, true 3-inch diameter pipe constructed from 304 stainless steel. Its CNC mandrel-bent design ensures maximum exhaust gas velocity, while robotically TIG-welded joints and heavy-duty flanges provide robust construction. This race-oriented downpipe is designed without a catalytic converter to eliminate restrictions and maximize horsepower gains and uninterrupted exhaust flow. It features universal flange compatibility, fitting factory or 3-inch exhaust systems, and retains O2 sensor bungs in their original locations. The design also allows for the use of OEM heat shields. All necessary hardware for installation is included, and the downpipe is built to OEM-level fitment standards. It is explicitly stated to be intended for racing use only. Skunk2 Racing emphasizes rigorous testing, including dyno, street, and race track evaluations, to ensure their products perform optimally in extreme conditions. This commitment to quality and performance is why top street and race cars worldwide rely on Skunk2 products.
