1. Using the supplied
Exhaust Attach Bolts,
temporarily attach the
exhaust manifolds to the
cylinder heads without
exhaust gaskets.
Note: If your cylinder
heads have exhaust studs
installed they will need
to be removed to fit the
2-into-1 exhaust.
5. Attach a loop-type line
support clamp (AN742
or equivalent) to the
firewall approximately
3" above the spring
clips on the exhaust
extensions.
6. Attach a spring between
the support clamp and
each exhaust extension.
It may be necessary to
shorten the springs for
your particular installa-
tion.

Trim the end of each exhaust manifold (arrow) as needed to
get the exhaust extensions to exit the cowl in the desired loca-
tion.
3. After each exhaust manifold has been trimmed to the
proper length, remove the manifolds from the cylinder
heads and re-install them with new exhaust gaskets (sup-
plied with the AeroVee 2180 engine kit).
4. Attach a spring between each pair of spring clips. It may
be necessary to shorten the springs for your particular
installation.
2. Slide an extension pipe onto each manifold. It may be
necessary to shorten the length of the exhaust manifold if
the extensions interfere with the firewall. Do not shorten
the expanded portion of the extension pipes.

7. Trim the ends of the exhaust pipes to final length. The
pipes must be long enough to ensure the exhaust gases
exit the cowl, yet pipes which extend too far below the
cowl will add drag and reduce your airspeed.
