Performance Exhaust Stainless Steels
An after market exhaust system will typically be constructed of either stainless steel
or coated steel tubing. Stainless is preferred but is also more expensive. You'll
typically find 4 varieties of stainless steel used in performance exhaust systems:

How a High Performance Exhaust System Gives You More Power & Better
Performance
It's been proven on the street and the strip; weather you've got a 10 year old
Honda Civic, or a brand new, 2008 Chevy Silverado, a new high performance
exhaust system is one of the most cost effective performance mods you can make.
Many people think a high performance exhaust system increases your engines
horsepower by flowing as freely as possible. While that may be true to a point,
especially when dealing with the popular, aftermarket, cat back exhausts, there is far
more to it than that.
An exhaust driven performance increase really begins all the way at the front, where
the exhaust system connects to your engine. The part of the exhaust that actually
connects the engine to the exhaust pipe assembly is called the exhaust manifold.
The manifold gets the exhaust gas from the exhaust ports in the cylinder head(s) to
the pipe that transports the exhaust to the rear of your car.
In many vehicles, these are made from cast iron for cost and durability reasons.
Cast iron lasts a long time, is easy to produce, quiet, and works well enough for
most o.e.m. applications. One of the first performance modifications usually
performed in attempt to increase power is to replace the factory manifold with an
aftermarket unit.
The most popular type of manifold seen in the aftermarket is a tubular unit known as
a "header". The principal difference between headers and the standard factory, cast
iron manifold is that headers are mostly manufactured from steel tubing. This allows
several benefits:
1- Tuned lengths - Usually the engine tuner wants the length of each header pipe
that tuns to the exhaust pipe (known as a primary tube) to be equal. During the
design process, the combination of length and diameter of the primary tubes is
chosen to give the best performance in the desired RPM range.
Street oriented exhaust systems, even very high performance units, are usually
designed to deliver great performance in the middle to upper middle portion of a
particular engines RPM range. Racing systems, on the other hand, are designed
more with maximum power in mind. This usually boosts high RPM power at the
expense of low to mid range power and driveability.
The length and diameter tunes the exhaust by allowing the pulse created by the
expelled exhaust gas to collapse as it exits the tube. This creates a negative pressure
wave that travels back up the system toward the combustion chamber. As it arrives
at the exhaust valve, it aids in pulling out the spent combustion products. Changing
the diameter and length will alter the time at which the pulse arrives at the exhaust
valve, and thus the RPM range at which the motor will operate with the most
efficiency.
2- Weight savings - A steel tube header will usually weigh far less than its cast iron
counterpart. Weather for street or racing applications this is obviously desirable. Less
weight will translate to better performance, not only in acceleration and top speed,
but also better handling and braking. Since the installation of headers usually occurs
at the heaviest end of the vehicle, the lost weight typically results in better balance.
This is especially true on front drive vehicles, such as Civics, Accords, and other hot
imports.
After the exhaust manifold, on normally aspirated or supercharged cars there's a
piece of the exhaust system on most front wheel drive cars called the down pipe. A
very accurate name, this piece of pipe routes the hot exhaust gas down to where is
can make a 90 degree turn and head toward the rear of the car. These are another
area where added horsepower can be found. On turbocharged cars, the manifold
usually has the turbocharger bolted directly to it.
After the exhaust turns toward the rear of the car, it typically runs smack into the
catalytic converter. In the old days this was a choke point for the exhaust, but new
units typically flow much better. If you're after that last bit of horsepower, or you
have a forced induction motor, you can get a high flow cat to help maximize power.
An after market exhaust system will typically be constructed of either stainless steel
or coated steel tubing. Stainless is preferred but is also more expensive. You'll
typically find 4 varieties of stainless steel used in performance exhaust systems:
- T-321 - The Ne Plus Ultra steel for exhaust system use. Normally used in
aircraft parts and premium racing exhaust applications, it has titanium alloyed
with the steel for extreme corrosion resistance and impressive strength. It also
is very strong and fatigue resistant when facing the extreme temperatures
found in exhaust systems. You will normally have to get a system custom
fabricated using this material. - T-316L - An extra low carbon stainless steel with a high chromium content.
Often found in marine applications, where it's impressive corrosion resistance
is very important. - T-304 - A great blend of strength, corrosion resistance and value. Yes, T-304
is not as well suited to exhaust system applications as either T-321 or 316L,
but it's far less costly. For many applications, especially high performance
street machines, that's a great trade off. There are 2 varieties of T-304
stainless most commonly used in exhaust systems; A-554 and A-269. A-554
is stronger, but A-269 is fully annealed. Annealing is a heat treating process
tghat relieves internal stress and makes the material easier to work with. - T-409 - 409 is the least expensive type of stainless steel normally used in the
manufacturing of high performance exhaust systems. It doesn't have the
strength or corrosion resistance of the 300 series materials. It lacks the nickel
of the 300 series, so it isn't as heat resistant either. That being said, T-409 is
still a fine material for general purpose exhaust system applications.
Performance enhancing features to look for when shopping for a new exhaust
system:
- Diameter - In order to improve performance, your new exhaust should be at
east 1/4" - 1/2" larger in inner diameter than your current system - Mandrel bending - This method of bending exhaust tubing prevents power
robbing restrictions by keeping the tubing a constant diameter, even
through the bends in the tubing. Non-mandrel bent tubing will be reduced in
diameter through the bends, causing a restriction in the exhaust flow.
