The MagnaFlow Street Series axle-back (part 19558) is a bolt-on rear exhaust section for the 2.7L twin-turbo V6 Bronco. It routes exhaust through mandrel bent 2.5" main piping into a large straight-through muffler before exiting through dual 4" black powder coated tips, and the rear exit is a dual split configuration. The manufacturer says it is made of durable stainless-steel construction backed by MagnaFlow's limited lifetime warranty. Where it earns its price is versus the factory muffler: the manufacturer states it was tuned to produce superior interior and exterior sound levels, and it uses extensive use of 3D scanning during development to ensure OEM-like fitment. Owner discussions on user forums are mixed on how much a V6 gains from an upgrade, so listen to sound clips before you buy.
This kit is for the Bronco 2.7L EcoBoost V6, not the 2.3L. CNC precision manufacturing and 3D scanning guarantee a direct-fit design for the 2.7L, and the manufacturer lists 2.3L applications under a separate part number. Search terms buyers use include "2021 Bronco 2.7 axle-back exhaust," "MagnaFlow 19558 dual split rear," and "Bronco V6 black tip axle-back." Installation is a bolt-on job. The manufacturer says it may require basic automotive knowledge for proper installation and professional installation is always recommended.
The manufacturer says the direct-fit design fits any Ford Bronco equipped with the 2.7L twin-turbo V6. The manufacturer's own pages list different year ranges, so check your VIN with the manufacturer's fitment tool before ordering.
No. The manufacturer's 2.3L Street Series axle-back is a separate part number, 19555, built for the 2.3L turbo I-4.
The manufacturer says the kit includes all the hardware necessary for do-it-yourself installation. However, its spec list shows clamps as not included, so confirm the full contents with the manufacturer before installing.
The manufacturer describes this as a bolt-on installation with clamp-on inlets and hangers included. Because clamps are listed as not included, check that you have them on hand before you start. Download the manufacturer's installation guide for the tool list and torque details, since the sources I reviewed did not include a specific tool list. Plan for the stock muffler section to come off completely, and inspect the factory hangers and mounting points before fitting the new system.
