Original Exhaust System Removal
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. Figure 1 1. 2. Unbolt and remove the center support bracket as shown in figure 1. Measure back from the weld at the rear of the catalytic converter 5 1/4 on the right (passenger) side pipe and mark as shown in figure 2 and measure back 11 from the weld at the rear of the catalytic converter on the left (driver) side pipe and mark. Using a reciprocating saw or a chain style pipe cutter, carefully cut both pipes at the marks. Remove the vacuum line from the valve located at the rear of the vehicle as shown in figure 3. Lubricate all the hangers and rubber isolators. Using a muffler stand or an additional person to hold the exhaust up in place, remove the hangers from the rubber isolators and remove the exhaust from the vehicle as shown if figure 4.

1. Place a clamp over each expanded end of the X-pipe assembly and set it up into position as shown in figure 6. Tighten the clamps to 32-35 ft. lbs. Place a clamp over the expanded end of both left and right over axle pipes and set them into position as shown in figure 7 making sure to install the hangers into the rubber isolators. Do Not tighten the clamps. Using the original hardware install the center support bracket as also shown in figure 7. Place the vacuum plug provided into the vacuum line. Using the retaining clip already on the vehicle, mount the hose as shown in figure 8 so it will not come into contact with the exhaust. Place a clamp over the expanded end of the muffler assembly and set it up into position as shown in figure 9 making sure to install the hangers into the rubber isolators. Do Not tighten the clamps. Check your exhaust system for proper clearance under the vehicle and also for tip alignment. Once position has been determined to be correct, tighten the Accuseal clamps to 32-35 ft. lbs. Before starting your vehicle, make sure to check all wires, hoses, brake lines, body parts and tires for safe clearance from the exhaust system. Start vehicle and check for any leaks.
