Decades of race engineering are incorporated into every part Skunk2 develops. Built to fit the ’16-’20 Honda Civic 1.5T engine, our Alpha downpipe features the same level of quality and craftsmanship found in all our products. Featuring a large, true 3- in. 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.
