The entire system is increased to a dual 3” (72mm) exhaust path. With the exhaust valves open, the exhaust gasses travel uninterrupted from the front of the system out through the exhaust tips. When exhaust gasses travel into the multichambered rear muffler / resonator, they continue uninterrupted and a Helmholtz resonator reduces drone frequences without restricting flow on the open-valve path. With the valves closed, exhaust gasses travel through a sound reduction path via a smaller 2.5” (63.5mm) pipe, reducing volume and allowing the system to act more civilized when needed. Finally the system terminates via oversized 8.23”x4.76” (211x21mm) RS-style oval exhaust tips. The tips feature a diamond black finish and a subtle APR logo for a refined touch.

  • Smooth transitions and straight-through components maximize performance by reducing restrictions.
  • Complete catalyst-back system including downpipes, extending from the factory catalyst back.
  • Precision brackets and slip clamps ensure accurate alignment and hassle-free installation.
  • Premium T304 stainless steel construction with TIG welding for strength and durability.
  • Strikes the perfect balance of power, sound, style, and quality for enthusiasts.
  • Performance gains of 9 HP and 16 FT-LBS of torque delivered to all four wheels.
  • Valve-controlled rear mufflers dynamically adjust sound based on driving style.
  • Integrated Helmholtz resonator minimizes drone and enhances sound quality.
  • Optimized flow through dual 3.0” piping with quad exits into dual tips.
  • Dual 8.23”x4.76” RS-style diamond black oval tips with APR logo.
  • Fully emissions compliant for worry-free operation.
  • Mandrel-bent brushed piping for a refined finish.
