Note: With a used vehicle, we suggest a penetrating spray lubricant to be
applied liberally to all exhaust fasteners and allowing a significant period of time
for the chemical to lubricate the threads before attempting to disassemble.

2. Loosen the (2) clamps shown in the Figure 2 located just in front of each muffler assembly.
