Listed here under the MagnaFlow name, this BRExhaust-built kit (106-0138) is a direct-fit replacement for the 2.9L V6 Ford Bronco II, covering the 1986-1989 Ford Bronco II 2.9L exhaust system. The manufacturer says it is engineered for OEM F5YV8542AB exhaust replacement, so it is meant to slot into the factory mounting points as a complete, bolt-in system. Compared with the stock setup, the manufacturer points to aluminized steel construction and mandrel-bent piping, claiming better flow than the crush-bent pipes commonly used in competing aftermarket replacement exhaust systems. The kit also leaves all emissions equipment intact, maintaining emissions compliance, and carries a two year, unlimited mileage warranty. Owners on user forums have long said direct-fit exhaust options for the Bronco II were scarce, which makes a complete bolt-on kit a practical alternative to a custom fabricated pipe.
Installation is aimed at the home mechanic. The manufacturer states that no bending or welding is required for installation, and the multi-piece design can be installed around obstacles such as axles, crossbars, and brackets. Gaskets, U-bolt clamps, and a nut and bolt kit ship in the box, and the installation instructions come packaged with the parts. Searchers looking for a no-weld 1986-1989 Bronco II 2.9L exhaust, an aluminized bolt-on Bronco II cat-back replacement, or a direct-fit Bronco II muffler and tailpipe upgrade will find this kit fits that brief.
No. The manufacturer's specifications list both hangers and a mounting bracket as not included, so plan to reuse or separately source your existing hangers.

The manufacturer presents this as a bolt-on, do-it-yourself job with no cutting or welding, so the work is mainly unbolting the old system and clamping the new pieces in place. Before you start, check the factory hangers and rubber isolators, since you will need to reuse or replace them. Owners on user forums report that the 2.9L's exhaust manifold bolts can snap during removal, so soak the fasteners in penetrating oil well ahead of time. Dry-fit the sections loosely before tightening the U-bolt clamps, and confirm clearance around the axle and crossbar before final torque.
