SIDE PIPES
For the under-car system see page 138.
The E.R.A. 427SC was originally designed using an
original set of Cobra 427 side pipes. When we lengthened
the drivers-side footbox, we had to change the primary
pipes to fit. Exhaust systems are available from E.R.A. or
the suppliers listed on page 28.
The outside pipes are available in bare steel or stainless
alloy.
After the brackets are welded on , the bare steel
can be painted with a VHT type coating (usually must be
re-done every year), ceramic (HPC, Jet-Hot, Airborn
Coatings, etc.) or chrome plated. Stainless pipes will
discolor slightly to light gold. Chrome plating will turn
blue only on the hottest sections of pipe.
We recommend that the primary pipes be ceramic coated .
This decreases the heat radiated in the engine compartment
and extends the life of the pipes. Because of the slip fit
into the side pipes, mask the last 1
1 /
2
" of the outside
surface before coating.
While ERA specifies extra heavy flanges, the primary
pipes may have distorted during welding. Use a flat
surface to check their condition. If there is more than
.020" variance from flat, grind, file or mill the surfaces.
Note! Ford numbers the cylinders on the FE engine 1-4 on
the right (passenger’s side) bank, 5-8 on the left side).
The E.R.A. supplied primary pipes may differ from standard
Ford practice and be numbered (from the front) 1-4 on the
left bank, 5-8 on the right.
The 4 longer primary pipes are for the left side.
E.R.A. can optionally weld the brackets onto the side and
primary pipes at the factory.
WELDING THE SUPPORT BRACKETS
Install the primary pipes on the engine, leaving the bolts
slightly loose.

Support the pipes as shown, parallel with the bottom edge
of the rocker. Leave about 1

-2" between each side pipe
and the rocker panel. A soft-faced dead-blow hammer
helps get the pipes all the way on.
