Vehicle Fitment

You will have to measure and cut your current exhaust for this to fit. We recommend welding the muffler in place. However, you can also clamp them on. Clamps are NOT included. 

Product Features

  • Straight-through flow path for maximum performance

  • Stainless steel construction for lifelong protection (unpolished)
  • Internal stainless steel mesh & fiberglass construction to withstand harsh conditions and advanced technology to absorb unwanted interior resonance.

Muffler

Works great! About the same sound as factory. Fit was excellent for the pipes.

Excellent Product

Quality muffler with perfect fit & finish. When driving casually, the sound of the exhaust note is deeper than stock and not loud. When you really get on it, the sound is impressive.
