About the manufacturer

The 80 series is a cross-flow design for applications where the muffler is mounted transversely behind the rear end. The inlet is located next to one of the outlets 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 Camaros and Firebirds with transverse mufflers. Constructed of 16 gauge 409S stainless steel and fully MIG welded for maximum durability.
