Pypes Performance Exhaust SGN13 - Manual

SGN10/ SGN13
409 Stainless Steel header/cross-member back exhaust system for
1962-1967 Chevy II/ Nova
(Some applications may require the installation of
a double hump cross-member)
SGN10: 2-1/2” w/ x-pipe
SGN13: 3” w/ x-pipe (coming soon)
1. Begin by placing the vehicle on a lift or four jack stands at maximum height to aid
in an easier installation. To help ease the installation, pre-fit all the components into a com-
plete system on your garage floor, using the diagram provided.
2. First, remove the existing exhaust system from the headers or exhaust manifolds
back. You can also remove any hanger mounted to the frame as your new kit includes fac-
tory reproduction hangers.
3. Now it’s time to install your new components. Begin by test installing your new
tailpipes. Since this system uses universal style hangers, you will need to find an appropiate
location to mount them. The tail pipes hangers will mount to the outside of the frame rails
just behind the rear tires. The muffler hangers will get mounted to the rear seat pans just
in front of the rear. If you so choose, custom hangers may be fabricated, let your creativ-
ity shine. These tails are designed to exit in between the rear tires and the rear bumper.
Optional polished tips will be required to allow the gasses to exit the body of the car.
4. Now, install the mufflers. The inlet should be closest to the drive shaft and the
outlet should be towards the rockers of the car. The clamp attached to the hanger at the
backside of the muffler will be the only connection clamp used.
5. Next, its time to install the x-pipe. This is where trimming of the tubing may be re-
quired for the optimum fit. Install the rear “X” member into the mufflers first. You are aiming
to have the center “X” land approx 8-12 inches behind the tail shaft of your transmission and
centered under the driveshaft. Also, the center plate on the “X” has an arrow stamp which
must point forward. Trim the rear legs as needed to put your “X” in the proper location. Quick
tip: If the rear suspension is unloaded, you can push the center “X” up until it just about
touches the drive shaft as it will never hit once t he suspension is loaded. Slide the front legs
into the x-pipe. They should end somewhere close to the humps in your transmission cross-
member. On some applications, the front “X” legs may not be centered in the humps but
line up to your headers or down-pipes. This is fine as the system will not hang too low. Be
extra careful when measuring and cutting. A helpful tip: Line up the front legs under the cen-
ter “X” to mark your cut lines making sure to line them up with you headers or down pipes.
6. Last, finish the system by connecting the front legs of the x-pipe to the headers
(collector reducers) utilizing the two 1ft collector extension pipes. Trimming the length will
be required. Do not connect the x-pipe directly your headers. If down pipes (see down-pipe
instructions) are used, make sure the end close to the rear side of the transmission cross
member. If they are too long they must be trimmed. Some header applications require
custom collectors due to the header not ending square and parallel to the car. For proper
system fit, you collectors must run parallel with your rocker panels.
7. Finish the system by making all your final adjustments to position the x-pipe, muf-
flers and tailpipes. Now tighten all the clamps (Warning: tightened clamps will leave marks
in the tubing, making removal or adjustments extremely difficult) 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.
Now it’s time to fire up that muscle car and enjoy your
new Pypes Performance Exhaust.
