The aFe Apollo GT 3-1/2 inch axle-back is a muffler-delete system for Ford F-250 and F-350 Super Duty trucks, and the manufacturer lists this version without a muffler. The pipe is constructed from 3-1/2" - 4" mandrel-bent 409 stainless steel tubing, finished with a 6-inch polished stainless tip. Searches for 3.5 inch 409 stainless muffler delete and F-250 Super Duty polished tip axle-back will land on this part.
Compared with the stock muffler, the case for this kit rests on its build and fit. The manufacturer says it was designed for custom, high tolerance factory fitment using computer-aided design, and the seams are 100% MIG-Welded for durability. aFe also positions the exhaust note as a throaty sound. Stainless construction is the main reason to pay more than a basic aftermarket pipe, since it resists corrosion over long winters.
The manufacturer's fit list includes Regular Cab / Long Bed - 142" Wheelbase, Super Cab / Short bed - 148" Wheelbase, and Super Cab / Long bed - 164" Wheelbase. Confirm your model year before ordering, because published application ranges differ between sources. For installation, the kit uses factory-style connections and hangers, so it bolts into the existing mounting points with no cutting or modifications, and all necessary hardware is included.
No. The manufacturer lists this part as the version without a muffler, so it works as a muffler delete on the stock pipe layout.
The manufacturer's fit list names Regular Cab with Long Bed (142" wheelbase), Super Cab with Short Bed (148"), and Super Cab with Long Bed (164"). Because published model-year ranges differ, confirm your year and configuration with the manufacturer before ordering.
The manufacturer describes this as a direct bolt-on installation that requires no cutting, welding, or modifications, with the hangers and clamps supplied in the kit. Because the mounting points are factory-style, the job is mainly removing the stock system and fitting the new pipe to the existing hangers. I did not find the manufacturer's install sheet during research, so confirm the step order, torque values, and any required tools against the manufacturer's instructions before you start.
