BILL OF MATERIALS
2 PVA12 Adapter
1 HFM80/XFM80 Mid-pipe
1 TFM Tailpipe Set
6 HVC24 Band Clamps
2 EVT57 or EVT57B Tips

1. Begin by placing the vehicle on a lift or four jack stands at maximum height.  

2. Unbolt your factory system cat-back by loosening the two butt connect clamps using a 15mm socket. Retain these clamps because they will be reused later in the installation.  

3. Once these clamps are loose the factory system can be removed in one piece. The use of a penetrating lubricant on the factory rubber insulators will aid in this step. There is no cutting required.  

4. Now it's time to start the installation of your new system. Begin by installing the two PVA12 adapters using two HCV24 clamps into the front of the HFM80/XFM80 mid-pipe. Next stall the mid-pipe assembly into the car reusing the two factory but connect clamps keeping all the clamps loose until final adjustment. Note: the mid-pipe has a support rod welded to the back of the mufflers. This rod should face the ground and mufflers tuck up nicely following the lines in the gas tanks.  

5. Next, install the TFM8OLF/TFM8ORF tailpipe sections into the factory rubber isolators then into the mufflers using two more HVC24 clamps at that muffler. The remaining two tailpipe sections TFM8OLR/FTM8ORR are easiest to install by running wire form hanger through the factory rubber insulators first and then connecting the slip fit joints. Use the two remaining HVC24 clamps at this connection followed by the tips.

6. Now that everything is installed loosely you can begin the alignment and tightening process. Making sure the mid-pipe is flat and follow the gas tank tighten the two clamps forward of the box followed by the factory butt connect clamps.  

7. Next tighten the tailpipe sections but only after you have the tips align in the openings of the valance. Tighten the tips and your installation is complete. Note: The use of air tools is highly recommended for these steps.  

8. Lastly, start your car and check for exhaust leaks. Condensation drips from the slip joints are 

Now it's time to fire up that muscle car and enjoy your new Pypes Performance Exhaust
