INSTALLATION INSTRUCTIONS
1. This Crossover is designed for cars with Long tube
headers for off-road use only! Start by removing your
old crossover at the collector reducers(front) and flow
tubes.(back) We recommend an ample dose of WD40
or other brand of penetrating oil to avoid stripping or
breaking the bolts at the header flanges. Remember to
disconnect both your front and rear O2 sensor
switches (if still connected) before dropping your
existing crossover.
Note: There are no hangers included with the X pipe
assembly. They are not necessary. Because your
Pypes X pipe is about 40 lbs lighter than the factory H
pipe, the header flanges as well as the muffler/tailpipe
hangers are enough to support the entire system.
2. Your Pypes crossover is modular allowing you to
resize both the length and width to attach to almost any
size long tube header. Take some measurements and
determine how much(if any) pipe will need to be cut
from the forward extensions or the ‘width’ middle
extensions. Cuts must only be made at the BACK of
these extensions and only if necessary. It’s always
best to cut less if not sure. You can always cut a little
more. Install the X pipe kit from the headers back. Do
not fully tighten the X connections. Use a stand to
keep the X in place. When you are satisfied with the
fit, tighten all connections.
3. Re-connect your O2 sensors. Be careful not to
twist the wires.
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 connections.
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.
