Performance Gains:

  • Adds 6 horsepower at 6600 RPM

  • Improved exhaust flow reduces backpressure

Key Features:

  • Premium 100% 304 stainless steel construction for corrosion resistance and longevity
  • Integrated Helmholtz resonance chamber eliminates interior drone at cruising speeds
  • Sportier, more aggressive exhaust tone without excessive volume
  • Twin 89mm (3.5-inch) polished or ceramic black exhaust tips with laser-engraved Dinan logo
  • Direct bolt-on installation using factory brackets and hangers

Autoplicity had what I wanted at the lowest price I could find and shipped it fast. The online ordering form was a little awkward to use as was calling customer service. I called customer service and the guy answered "yea".
