a kit with the mandrel bent tubing. So here is my question. How much more
performance does the mandrel bent tubing give you over what a local muffler
shops tubing? Would it be cheaper or better for me to purchase a muffler and
then go have a shop put the pipes on or am I better with the kit?

A friend of mine with a 91' Mustang was showing me an article in a magazine (I
think it was Muscle Mustangs and Fast Fords) about this topic. The article
compared a complete mandrel bent cat back exhaust system from Flowmaster to a
local exhaust shop's best custom job. Each system used the same size exhaust
pipe, the same mufflers, each exited in the stock location, and all this was
done on the same car. The custom job even eleminated a few bends used by the
stock and Flowmaster systems. The car was put on a dyno with each system and
the mandrel bent system beat the custom job by 12 hp and a similar amount of
torque.
Granted this was on a Mustang and not a Dakota, and I know that the Mustang
has a hell of alot more bends in its exhaust than we have in ours, but it
still seems to me that if you're going for performance and not just sound,
mandrel bends are the way to go.
