About the manufacturer

This 80 series muffler is a cross-flow design for applications where the muffler is mounted in front of the axle. The inlet is located next to the outlet on the same side of the case. Delivering an aggressive muscle car sound both inside and outside the vehicle, this is an excellent replacement for cars and trucks that want a side exit style system in front of the rear tires, similar to the AAR Cuda exhaust systems. Constructed of 16 gauge aluminized steel and fully MIG welded for maximum durability.
