The Skunk2 MegaPower Double Barrel (DB) Exhaust System for the 2017–2020 Honda Civic Si Coupe 1.5L delivers the aggressive sound, precision craftsmanship, and proven performance that Skunk2 is known for. Developed through decades of race engineering, the MegaPower DB system is designed to maximize exhaust velocity and eliminate restriction, improving horsepower, torque, and throttle response.
Constructed from 304 stainless steel, the exhaust features CNC mandrel-bent tubing, precision robotic TIG welds, and unrestrictive resonators for a smooth flow path from end to end. The system’s dual polished race mufflers with 100mm tips create the signature deep, sporty Skunk2 tone while maintaining daily drivability.
Each kit includes new adjustable exhaust hanger hardware, flange gaskets, bolts, and nuts for a precise, leak-free installation. The MegaPower DB is a bolt-on system that requires no cutting or welding and is compatible with the factory downpipe or Skunk2’s Alpha Downpipe upgrades.
