It
would seem that the ideal racing exhaust setup is predicated upon what type of
car you’re driving. But there are rules that every driver follows, such as how
to go about replacing the stock system, what type of parts, what pipes, what
materials, so on…so on…and so on. All you hear about down at the shop is how
folks young and old are chucking their cats, installing test or down pipes, and
then zipping out the door to show off their mods at the local dirt track. But
why? What kind of gains can you really expect from shuffling out OEM exhaust
parts in a WRX or 370Z? Is it enough to gut the system and make that level of
commitment? For many, it certainly is.

| Invidia G200 Catback Exhaust |
If
you took a poll of your fellow custom colleagues, what would the percentage be
of drivers who made at least one change to their exhaust? Would it be fair to
guess somewhere around 70-75%? Would you say three FR-S owners out of four have
done at least something to the
exhaust, whether it be an entirely new Invidia catback system or maybe
just latched on new exhaust tips? The point is, most sport compact drivers do
something, no matter how big or small, to their exhaust system. It doesn’t
matter if it’s to lockstep with more horsepower or because you want to sound
all tuned up on the city streets, the factory exhaust in any racing model is
going to get upgraded.
Concentrating
on the exhaust network and discounting other additions such as flywheels,
short-shifters, and clutches, it is easy to see how much performance increases
when airflow restriction is lightened. But the thing is, with Invidia exhaust
systems, one part here can make a difference, another part there can make a
difference, but when you completely overhaul the factory configuration, the
difference is ginormous. An Invidia test pipe
might kick in a few horses and punch things up a bit, maybe a high catted
downpipe opens up exhaust flow for an added boost, but when you install a whole
new catback exhaust system and supplement with Invidia downpipes and up pipes,
the percentage of performance increase climbs between 10-15%. That is what is known as a “checkered flag”
difference.
Combining
an Invidia exhaust system and test pipe is becoming a more and more popular
setup for racers, as in competitive racers who drive on racetracks. Finding the
right way to do up the exhaust to fit a racing profile comes down to individual
preference as much as anything else. You also have to take into account the
other components you have added to your car, how the car has been performing in
test runs, and so forth. It is always a good idea to do test runs, even on an
informal scale prior and after manipulating the exhaust, especially since not
everyone has access to a dynamometer. At least this way, you will get a better
gauge on where your car is at and if you need additional tweaking.
UltraRev has a wide selection of racing
exhaust parts from Invidia including catback exhaust systems, test pipes, down
pipes, and front pipes. Invidia
exhaust parts are recognized throughout the racing and tuner industry for
their wide diameter pipes and stainless steel construction. There are plenty of
parts available for the Subaru WRX STI, Scion FR-S, Subary Legacy GT, Honda
S2000, Subaru Forester XT, the Infiniti G35, and more.
