Truck still retains the factor muffler and catalytic converters. I clamped the flapper valve so that it's always open, cut off the factory resonators and installed new 3" pipe with MBRP T5182CF/T5183CF Carbon Fiber 4" OD Dual Staggered Wall Exhaust Tips....Oh, and a surprise cameo by a 1985 squarebody at the end.
