Aero Function Exhaust Systems

Exhaust Systems by Aero Function. This replacement rear muffler section lets you swap out your original rear muffler with a redesigned piece that routes dual exhaust out through one middle section with a 3-pipe center design similar to exotic performance cars. Mounting instructions and all necessary hardware are included.


  • Mild steel construction underneath chrome finish ensures corrosion-resistant protection
  • Clamps on with no welding required
  • Designed for use with Aero Function rear bumper pieces
  • Advanced construction methods ensure a tight, rattle-free fit
  • Custom sized to fit onto your specific vehicle's OEM exhaust pipe
  • Comes complete with all clamps and detailed instructions for installing
  • 3-year manufacturer warranty

Give the rear of your vehicle the look of a rear-engine exotic performance car with Aero Function's replacement rear muffler section. Designed for dual exhaust systems, it routes two factory pipes into one rear muffler, then channels gasses out through three exhaust pipes located in the center of your rear bumper area. When it comes to materials that exhaust components are made of, only tempered, high quality steel will stand up to the constant barrage of humidity, dirty road grit, salty slush, and very hot temperatures these parts face. Aero function crafts their custom rear muffler sections out of the toughest steel, then finishes it with a chrome outer layer that's polished to dazzling perfection. Clamp-on installation involves no welding, and the muffler section is pre-sized for an easy fit onto your vehicle's stock exhaust system.
