Installation Notes
Compatible With 2000-2005 Chevrolet Blazer, N/A; 2000-2004 GMC Jimmy, N/A; and 2000-2001 Oldsmobile Bravada, N/A. Fitment notes indicate use with 36163 and that welded assemblies require replacement of all required parts. Verify inlet and outlet orientation, flange style, and exhaust routing before installation. This muffler uses a 2-bolt welded flange inlet and pipe-connection outlet configuration, so matching the existing exhaust layout is important for proper alignment.
