Product Details

The Bosal BRExhaust Direct-Fit Exhaust Muffler Assembly 278-757 is part of the BRExhaust Direct-Fit Exhaust line, a product series focused on OE-style replacement fitment and factory-like exhaust tone. This muffler assembly uses aluminized steel throughout the muffler and pipe sections, with a fully aluminized finish to help resist corrosion in everyday driving conditions. The internal muffler design is engineered for quiet operation while maintaining exhaust flow characteristics suited to a direct replacement on the rear of the vehicle. For shoppers searching for a 1996 Subaru Legacy rear muffler assembly, a 1997-1999 Subaru Legacy exhaust muffler replacement, or a Bosal 278-757 direct-fit muffler for Subaru Legacy, this part is built around those exact fitment needs.

Fits 1996-1999 Subaru Legacy, rear.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Exhaust noise from a worn or rusted rear muffler
• Corrosion damage in the muffler body or pipe section
• Restricted exhaust flow caused by internal deterioration
• Factory exhaust tone that has become louder or uneven
• Fitment issues from non-direct replacement exhaust parts

Installation Notes and Tips

This muffler assembly is designed for direct, bolt-on installation with no modifications required. Verify rear-position fitment on 1996-1999 Subaru Legacy applications before installation, and confirm flange alignment and outlet routing against the existing exhaust layout. Because the assembly uses a flanged inlet, matching the flange connection and exhaust hangers during removal and replacement helps support a proper seal and correct positioning.

Quality Assurance

Built by a leading OE supplier, this Bosal muffler assembly is engineered to deliver OE-style performance, corrosion protection, and controlled exhaust sound for the Subaru Legacy platform.
