INSTALLATION INSTRUCTIONS
1. Start by removing your old mufflers and tailpipes. Save your hangers! We recommend an ample
dose of WD40 or other brand of penetrating oil to avoid stripping or breaking the bolts at the flange.
You will probably have to cut the tailpipe off to remove it.
2. Install the Tailpipes FIRST(figure A/B) and then the mufflers and Flow Tubes without tightening any
of the connections. (On some Mufflers there is an inlet and outlet! (ie: Pro V & FlowMaster) The Flow
Tubes provide for flexibility of fit between mufflers and tailpipes. Rotating them changes the position of
the mufflers and consequently the tailpipes. Experiment with the flow tubes rotating them until a
satisfactory position of both the mufflers and the tailpipes is achieved.
Note: Some might need to trim the Flow Tubes to length.
Tip: Using WD40 or other lubricant on the pipe ends will make slip fit and rotating of pipe easier.
3. While holding everything in place, begin to tighten all connections. Remember, once a U-clamp is
tightened securely (at mufflers), it is very hard to separate the pipes at this point! So be very careful
you are satisfied with the position of the mufflers and tailpipes before you fully tighten. Look for clear-
ance and proper height all the way around each muffler. Look to make sure tailipipe is not hitting tire or
other obstruction. Stainless tips will be very close to bumper. This is ok.
Notes: 1979-1985 Models will require a 1986 > dual hump crossmember and short tube headers. If
you plan on switching mufflers at any point, it is highly recommended that you purchase stainless steel
band clamps. Pypes #HVC20. Similar band clamps may be purchased at your local NAPA store.
4. Start engine and listen and look for leaks. Black deposits at any junctions indicate an exhaust leak.
5. After driving the car for approximately 50 miles, check the system for any possible loose connec-
tions.
The first time you warm up the exhaust system you will notice quite a bit of white smoke. This
is normal! It is the Mandrel fluid used to bend the pipes that has not evaporated.

Position the tailpipes as shown (figure A) then moving forward once the wire hanger is past the axle
shaft twist in a clockwise manner to install tailpipe. Wide tires may require the need to remove the
wheel to install
