The Skunk2 Alpha Downpipe is a high-flow, precision-engineered exhaust component designed for the 2018–2021 Honda Civic Type R. Built with full 304 stainless steel, this true 3″ (76 mm) downpipe delivers superior exhaust flow, durable construction, and a performance-focused fitment that complements both OEM and aftermarket exhaust systems.
Mandrel-bent tubing ensures smooth gas flow through every section, while robotically TIG‑welded joints, robust flanges, and an integrated stainless flex section provide a leak-free and vibration-tolerant assembly. This version includes a Max Flow 100‑cell catalytic converter to balance emissions compliance with minimal flow restriction. O2 sensor bungs are located in OEM positions, and the downpipe is compatible with factory heat shields and mounting points.

Installation hardware (gaskets, bolts, flanges)
Instructions as needed
Recommendations & Notes:
Best paired with the Skunk2 MegaPower Double Barrel DB Exhaust (P/N 413-05-6075) for optimized flow and sound.
This downpipe is labeled as “special order / not CARB legal” in some listings, so confirm local emissions compliance before use.
Because it’s a cat version, it offers a balance between flow and emissions, but removing or replacing the cat may be considered for full race setups.
