This is the Corsa Performance Sport Exhaust system for
the new F-150. The kit comes in single side exit or dual
rear-exit (PN: 14372) as we opted for. A variety of tip
choices
are available, we chose the twin 3.5" assembly. |
Corsa systems are not cheap by any means. But at $700-900
a system you get 100% 304
grade stainless steel front to back. It goes without
saying this is all mandrel bent piping. Two sound choices
are available, the Sport mufflers is aggressive and the
Touring is a bit milder. We went all out, listen to the
Sport kit for yourself in the sidebar on page 1. |
A look into the Corsa Sport muffler shows a straight thru
pipe. The quarter-size openings for the sound waves are
also visible at each end.
|
F150 exhaust systems have had the same layout for decades.
However on the new F150 the catalytic converters and 2.5"
Y pipe are pretty high-flow. The restriction is downstream
at the muffler. |
Corsa exhaust kits come with OEM Style TORCA clamps and
fabricated hangers for the dual pipes under the bumper.
Unlike conventional clamps these don't slip or flare out
the pipe when properly torqued to 45 ft.-lbs. |
The guys at Mel & Sons in San Pablo, CA did the dirty
work for us. Standard exhaust system installation principles
apply here. Get the factory muffler and pipes out and
get the new parts in. Save the hangers they'll be reused. |
The Corsa muffler gets positioned such that the condensation
weep hole is at the rear and facing down. As with any
exhaust kit get everything loosely assembled and lined
up before clamping or welding. |
One the rear-exit systems Corsa has developed this ingenious
bracket to hang the pipes. The bracket simply mounts under
the upper bolt on the leaf-spring shackle. |
Feed the dual pipes over the axle and into the Y split
adapter at the rear of the muffler. Note that the pipes
will be in a stacked position in this system, not side
by side as is often seen in a dual-out muffler.
|
Use the supplied zip-tie to secure the axle-vent tube
from possible contact with the driver-side over-axle pipe.
Corsa instructs to move the tube behind the brake lines,
however we found that just tying it back provided sufficient
clearance. |
A look at how the Corsa system fits under the F150 before
we drop the vehicle down. It's a shame all this stainless
steel will be out of sight! |
All the guys at Mel & Sons take pride in their work,
so it is imperative the tips line up perfectly. Along
with the Corsa sound the quad tips are the distinctive
indicator that this F150 is not stock.  |
