Pypes Performance Exhaust SME11S - Manual

SME11S
409 stainless steel header/cross-member back exhaust system for
1970-1974 Barracuda E-bodies
SME11S: 2-1/2” System w/ x-pipe
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 complete system on your garage floor, using the diagram
provided.
2. First, remove the existing exhaust system from the headers or the ex-
haust manifolds back. You can also remove any hanger mounted to the frame as
your new kit includes new hangers.
3. Now it’s time to install your new components. You will be starting from
the back of the car and working your way forward. Begin by installing the new
tailpipes. Temporarily hang the tails over the rear axle. These tailpipes are de-
signed to mount in the factory rubber tail pipe hanger. If they are not present you
can utilize the universal rubber strap style hangers provided. Slide the mufflers
onto the tailpipes placing a support under them. You will be clamping a hanger
to the back of the muffler neck and attaching it to the under body of the car. In
some applications, your factory hangers may be used.
4. Next, install the x-pipe. This is where trimming of the front legs may be
required for the optimum fit. Install the fixed rear legged “X” onto the mufflers
first. Your center “X” should be positioned approx 8-12 inches behind the tail
shaft of your transmission and centered under the driveshaft. Also, the center
plate in the “X” has an arrow stamp which must point forward. Next, slide the
front legs into the x-pipe. They should end somewhere close to the humps in
your transmission cross-member. These may need to be trimmed to fit the width
of your headers or optional down-pipes. Narrowing width will require trimming to
leg as it slides into the center “X”. Be extra careful when measuring and cutting.
A helpful tip: Line up the front legs under the center “X” to mark your cut lines
making sure to line them up with you headers or down pipes. Finish the system
by connecting the front legs of the x-pipe to the headers (collector reducers)
utilizing the two 1ft connection pipes. Trimming the length may be required. If
down pipes are used, make sure they end close to the rear side of the transmis-
sion 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 in the car. For proper system fit, you collectors must run parallel with
your rocker panels.
5. Finish the system by making all your final adjustments to position the
x-pipe, mufflers 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 steel system
can be welded with your standard mig welder, and is highly recommended when
possible.
6. Note: This kit requires the use of PYPES tip number EVT87 and EVT86,
or one similar to exit properly through the valance cutouts.
Now it’s time to fire up that muscle car and enjoy your
new Pypes Performance Exhaust.
