The aFe Apollo GT Series 3" Hi-Tuck Axle-Back Exhaust (49-43147) is a 3-inch system built from mandrel-bent 409 stainless steel tubing and 100% MIG-welded seams. It routes exhaust through a high-flow 304 stainless muffler and ends in a hi-tuck tip, which the manufacturer says lifts the tailpipe for extra clearance on steep climbs, descents, and rough terrain. It is made for the 2.3L EcoBoost four-cylinder and 2.7L EcoBoost V6 Ford Bronco. Compared with stock, the larger-diameter piping and the deep-toned muffler change the sound and exhaust flow, and the hi-tuck tip protects the system where a factory tip is more exposed. This is a good choice for off-road builds that need an axle-back upgrade without cutting the factory exhaust.
