The
stock exhaust system found in most cars and trucks is a soruce
of great flow restriction. By replacing the exhaust system,
you will discover a dramtic increase in power. The simple,
and most popular method to gain some power is to install a
cat-back exhaust system, which replaces the stock exhaust
from the catalytic converter to the tailpipe. These systems
incorporate a high-flow muffler and often use larger-than-stock
diameter tubing, which is mandrel-bent to eliminate crimping
when the tubes are bent. Several manufacturers produce cat-back
exhaust systems specially made for each model vehicle.
There
are a few important things to consider when choosing an exhaust
system. The material used in a cat-back system is usually
aluminized steel. Aluminized steel exhaust systems are cheaper,
but they won't last as long as stainless steel. For maximum
durability, and if you can afford it, choose a stainless steel
exhaust.
Exhaust
systems vary greatly in exhaust tone, noise, and fit. Keep
those things in mind when deciding on your exhaust system.
Another consideration is the exit location of the exhaust.
Several manufacturers offer rear or side exit systems. You
may also have the choice between single or dual-exhaust outlets.
If you plan on installing your own cat-back system, remeber
that although the new exhaust may be a simple bolt-on operation,
removal of your old system may require cutting.
If
a cat-back system isn't available for your vehicle, you can
purchase a high-flow muffler and fabricate your own system
using larger-than-stock tubing, or have your muffler shop
build one for you. A good cat-back exhaust or high-flow muffler
can add up to 15-20 horsepower to your engine, and may also
help with fuel economy.
For
a mild boost of power, start with a high-flow air filter and
a cat-back exhaust system. |
