Decades of race engineering are incorporated into every part Skunk2 develops. Built to fit the ’18-’21 Honda Civic Type R engine, our Alpha downpipe features the same level of quality and craftsmanship found in all our products.

Featuring a large, true 3-inch pipe diameter built from 304 Stainless Steel, each downpipe is CNC Mandrel Bent to provide maximum exhaust flow. Robotically TIG welded joints, heavy duty flanges and a high-quality stainless steel flex section ensure exact fitment and no leaks due to engine vibration and movement under extreme driving conditions. To ensure maximum horsepower gains and uninterrupted exhaust flow, this downpipe comes with a Max Flow 100 cell catalyst to keep flow restrictions minimal.
