The Gibson Dual Split cat-back for 1998–2000 Ford F-150 Base 4.6L delivers a throaty, aggressive tone while lowering backpressure to increase torque and horsepower—typical gains of 15–20 hp. Built of stainless steel with mandrel-bent tubing and polished slash-cut tips that exit out the back, it bolts on using included hangers without welding. The baffled Superflow muffler minimizes cabin drone and Gibson provides a lifetime limited warranty.
