1. Begin by placing the vehicle on a lift or four jack stands at maximum
height. This will aid in an easier installation.
2. Unbolt the existing system from just behind the factory h-pipe using a
15mm wrench on the band clamps. Loosen the clamps at the factory axle-
backs with a 15mm wrench. Now remove the factory mid-pipes. Last, unbolt
the factory muffler hangers using a 13 mm wrench and drop the axle-backs
from the vehicle.
3. You can now re-install the four axle back hangers on to the frame
rails. Leave the bolts loose until the entire system is installed.
4. It’s time to install your new Cat-back system. Begin by installing the
two 16” slight bent pipes to the factory h-pipe (straight end towards the h-pipe
and slight bend towards the mufflers) using the factory band clamps. Snug the
bolts with a 15 mm wrench.
5. Next install the new M-80 cylindrical mufflers onto the short pipe
(slight bend towards the mufflers and the straight portion into the clamps at
the h-pipe). The HVC21 band clamps will be used at both the inlet and outlet.
These will appear to be very close o the drive shaft.
6. Next, install the over the axle portion on the mid-pipes, and slide the
axle-back muffler delete tailpipe wire forms into the factory muffler hangers.
SFM66M uses the “PypeBomb” axleback to finish the system. Use an HVC21
band clamp at the connection between the mid-pipes and the tailpipes.
7. Finally, slide the EVT 52 tips on to the tailpipes, SFM66/69 only.
Clamp the tip on using a HVC21 band clamp.
8. Finish the system by making all your final adjustments to position
the mid pipes, mufflers and tailpipes. Now tighten all the band clamps or for
the best fit weld all the slip joints. The 409 stainless can be welded with your
standard Mig welder, and is highly recommended when possible.
9. Check all clamped joints periodically as they may come loose.
Note For V6 owners:
Please refer to the installation instructions
for XFM44 After-cat x-pipe. Use the passenger side as a reference for your
new GT hanger placement. Your car has all the threaded nuts welded into
the frame rails ( some 05-10 V6’s need the hole to be threaded with an M8
x 1.25mm tap). Proper placement is necessary. Also if you are still utilizing
your factory V6 rear bumper cover, you will need to trim out the opening on the
driver side, per the template provided.
Note:
If you find the new tips are not aligned properly in the bumper
cutouts, you may need to adjust your mid-pipes by loosening the two band
clamps located where your factory h-pipe meets the mid-pipes. A slight rota-
tion of the mid pipes will allow for the best fit.
Now it’s time to fire up that muscle car and enjoy your
new Pypes Performance Exhaust.
