Dyno Cell: Toyota Celica
Exhaust
Who's the
Top Dog?
By Staff
While I was at a tender age, my
parents taught me to take responsibility for my
own actions and not make excuses. As a tech
editor, you hear a lot of excuses from
manufacturers, particularly from companies that
make products that either don't work, don't make
power or don't fit.
In the July 2002 issue, the
"Tech Scene" column announced we were going to
conduct an exhaust shootout on our long-term 2000
Celica GT-S. We offered any exhaust manufacturer
who made a system for the Celica the opportunity
to get involved. By doing so, each would be
standing by their product, even if it didn't
produce the power levels they wished it would--no
excuses.
Surprisingly, our office was
flooded with systems from nine different
manufacturers who wanted to participate in this
first-time event for Turbo.
We elected to conduct the
testing with the following criteria: Weight, tip
diameter, sound at idle and 3000 rpm (normal
cruising), price and power. We tested each system
on a Dynojet chassis dynamometer back-to-back on
the same day. All the manufacturers who
participated were invited to the dyno facility to
witness the testing which gave the manufacturer
assurance no one would under-handedly get the
upper hand during the testing. All the names of
the manufacturers were placed in a hat and chosen
at random to decide the order of the testing. The
results of the shootout are listed below in the
order of the testing.
Who was top dog? They all
installed easily but, beyond that, we will let you
decide which parameters mean the most to
you.
