The aFe Scorpion 2-1/2in cat-back is a three-piece aluminized steel exhaust for the 2007-2017 Toyota FJ Cruiser V6-4.0L. The manufacturer says it is built from 2-1/2" mandrel-bent tubing, which it claims flows better than the factory system for more torque and horsepower. The stock system's restriction is the main reason to upgrade. An 18" baffled muffler keeps the tone deep and smooth under load, and the black, high-temp powder-coated 4-1/2" tip gives the rear end a finished look. The welds are hand MIG-welded, and the band clamps seal the joints across a full 360 degrees. This is a good match for owners searching for a 2007-2017 FJ Cruiser V6 cat-back, a 2.5 inch FJ exhaust, or a quiet-but-aggressive FJ 4.0 V6 exhaust.
Fitment is straightforward. The manufacturer's bayonet-style hangers match the OE mounting points, so you can install the system without cutting or modifying the factory hangers. The exception is TRD Special Edition trucks, where the rear skid plate has to come off before the system will fit. If you are running a skid plate or other underbody armor, check that the muffler and piping clear it before ordering. The installation is a bolt-on job for a home mechanic with basic hand tools and a way to support the exhaust while you work.
The manufacturer states that the OE-style bayonet hangers make installation easy with no cutting required.
The manufacturer notes that TRD Special Edition models fit only after the rear skid plate is removed.
The manufacturer says this system uses OE-style bayonet hangers, so it does not require cutting or welding to the factory exhaust. The band clamps and hardware are designed to seal the joints across a full 360 degrees. For TRD Special Edition models, plan to remove the rear skid plate first. Use the manufacturer's installation guide for the torque specs and tools.
