Product Details

This AP Exhaust muffler is built for vehicles that use a dual-exhaust layout and a Y-style muffler configuration. The 20-inch body length, 24-inch overall length, and center inlet/dual center outlet layout support the factory-style exhaust routing used on select 1991-1992 Chevrolet Camaro, 1991-1992 Pontiac Firebird with converter, 1995-1997 Chevrolet Camaro, and 1996-1997 Pontiac Firebird models.

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

Common Issues This Muffler Can Address
