SME10/ SME13

Stainless steel header/cross-member back exhaust system for

1969-74 Mopar E-bodies

SME10: 2-1/2” w/ x-pipe

SME13: 3” x/ 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 complete system on your garage floor, using the diagram provided.

2. First, remove the existing exhaust system from the headers or the exhaust

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 designed 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. Slide the mufflers on to the tailpipes. 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. The

muffler inlets should be angled in towards the driveshaft for connection to the rear legs

of the x-pipe.

5. 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. Nar-

rowing 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 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 in the car. For

proper system fit, you collectors must run parallel with your rocker panels.

6. 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. Stainless steel 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.
