This system replaces the restrictive stock exhaust for smoother flow, delivering dyno-proven gains of 9 wheel horsepower and 8 wheel torque on a stock 2015 WRX CVT with 93 octane fuel.

Key Features

  • Construction: Mandrel-bent 3-inch T304 stainless steel tubing with precision TIG welds in a four-piece design for optimal flow from 2-bolt flange to 2.25-inch Y-section.
  • Hardware Included: Two 2.25-inch V-band clamps, 3-inch band clamp, 3-inch 2-bolt flange gasket, and stainless steel bolts to prevent rust.
  • Power Gains: Dyno-tested increases of 9 whp and 8 wtq on stock tune while keeping safe air-fuel ratios.
  • Muffler Design: Dual oval mufflers reduce drone on highways yet amplify aggressive tone during acceleration.
  • Exhaust Tips: Quad 3.5-inch staggered double-wall polished tips enhance rear appearance and sound exit.
  • Direct bolt-on replacement installs in under one hour.
