INSTALLATION INSTRUCTIONS – # M31024

1. Raise and fully support the vehicle (a vehicle lift is recommended). If you do not have access to a lift, you may raise the rear using a jack/jackstands or by using drive-up type ramps.


2. With a Sawzall or other equivalent tool suitable for cutting metal, cut the factory mufflers off (both driver and passenger side) where shown in figure 1. De-burr the ends of the pipes left on the car.

3. Remove the factory mufflers from the vehicle by first removing the rearmost rubber isolator and sliding the mufflers out from the fixed isolator mounted to the chassis. A few sprays of WD-40 on the isolators will make this much easier.


4. Take the SLP muffler, slide a 2.25” clamp over the inlet side, and slide onto the factory pipe you just cut. Slide the hangers into the fixed isolator at the same time.


5. Install the rear-most rubber isolator to hold the mufflers up.


6. Repeat steps 4 and 5 for the other side.


7. Slide a 2.5” clamp over the inlet of the exhaust tip, and slide onto the outlet side of each new muffler. Repeat for other side.


8. Adjust system from front to back to allow for adequate clearance all around and tighten all clamps.


9. Test drive vehicle and inspect for any leaks.


10. The finished installation should look like Figures 2 and 3.
