What makes Hogan Performance and our products different? We are in the business of selling top
quality performance exhaust products at a reasonable cost. In an effort to
provide our clients with the best product possible. We have recently, put into
service a Trans-fluid Mandrel exhaust tubing bender. This bender, to our
knowledge, is the only Mandrel bender used for production, in the Midwest. Many
ask why more shops don’t offer mandrel bending. Quite simply, it is because
the equipment and tooling is extremely expensive. You may be asking yourself,
“what is a Mandrel bend?” Conventional muffler shops use a press bender to
bend tubing. A press bender, as its
name implies, presses the tubing in the center of the bend, which reduces the
inside diameter of the tubing in the bend. A mandrel bender has a series of
balls called a mandrel that are drawn through the inside of the tubing,
retaining tube diameter that is consistent through out the entire length of the
piece. The illustrations on the bottom of this page give you a visual depiction
of the difference between press bent and mandrel bent tubing. We are sure you
can see the value and performance
advantage. Dark
shaded area depicts flow through bends. Light shaded area depicts normal
inside diameter of tube. Mandrel bent pipes have a consistent flow area throughout bends and straight lengths.
What makes
our pipes better than the others found on the web? First of all, our flange is
custom made from 3/8 steel plate and have the gasket groove machined into it
just like the original equipment flange. Our pipes are mandrel bent, in house,
which means each pipe is made specifically for each individual unit. This means
that several bends are never cut and spliced together to form a single elbow.
Less welded joints means better strength. We can also manufacture special
orders with modifications to any pipe to fit your needs, and lastly every pipe
we build is 409 stainless steel.

DP series are made with 3 inch tubing.
