is sometimes located back alongside
the transmission. They crack, and we
change them all the time when install-
ing new turbos.
But you can help keep yours intact.
Just take it easy on the throttle, and
you probably won't have to call us

An
owner-operator
recently called
the shop.
He was upset because the
exhaust pipe flange, which
holds the pipe to the turbo-
charger, failed months after
we did some work on his
system.
However, we didn't
change the pipe coming
from the turbocharger; it
was his original flange that
failed. Flanges are wear
items, and they need to be
replaced from time to time.
However, the problem for
this owner-operator, and
possibly even for you, too, is
another lesson in something
I preach regularly: Take it
easy on the throttle, and
your engine – and your wal-
let – will thank you.
I teach people to drive as
if there's an egg between
their foot and the throttle.
Flanges take abuse, and that
is why there is flex-pipe in
all exhaust systems: to help
alleviate the torque of both
the engine and your right
foot.
Every time you accelerate,
the engine torques to the
right and tries to rip itself
off the engine mounts; thus,
the engine's torque twists the
exhaust pipe flange.
The flange has to hold
up the exhaust pipe until it
