NOTE: the list above just shows the
several brands and normal possibilities, however ALL systems will work on
either 3.4 & 3.8 with some modification which normally requires welding. A
good muffler shop can solve these problems, usually in less than 1 hour. So
putting a B&B system on the 3.4 is possible! There are people with an
adjustable V8 Borla system on their V6! So the imagination and the $$$ are the
only real limits here. An application on both the 2.8 and 3.1 might also be
possible with some modifications.
Should I get
a cat back system for more performance? Well, a cat back system
doesnt always guarantee extra hp when compared to just a muffler
replacement. When the engine is modified and benefits from a superior air
intake (better breathing), a cat back system will produce more power since the
aftermarket intermediate pipe is less restrictive (mandrel bend) and some are
less narrow (2.75 or 3 instead of just 2.5), besides that replacing
the stock intermediate pipe is always a good thing to do as the stock pipe will
look crappy really fast! Mind you that you could notice less torque due to
the reduction of back pressure. When you plan serious power upgrades which
include headers and maybe even a supercharger then a cat back will be a wise
decision! Replacing the muffler first and adding another intermediate pipe
later is also one of the many possibilities.
Which exhaust
system is the best for the price? Well, it depends on what
youre looking for! In the overall sound/power/looks department the SLP V8
takes 1st place! Why? Well at $80 including shipping, and adaptor it simply
cant be beat! The Flomaster picks up a good second place! The Decoma F1
system scored big points in the power department, but, unfortunately they
stopped producing them. As far as looks and sound is concerned it really
depends on personal taste, but the Borla system is very popular even though it
doesnt come cheap!

Which exhaust
will give me the best V8 sound? Well, a question like this will
start discussions that will never end. Listening to several exhausts is the
only way to found out. However from experiences from several members who had
been through several exhausts the Borla seems to be a very good choice. It is
deep at lower rpms, and sounds like a real sports car at higher
rpms without being obnoxious. According to list, Flowmasters seem to be the
loudest, but they tend to sound Ricey (Screaming like a 4
cylinders) at high rpms .. A comparison test is really the only way to go! Go
to car shows and check them out , ask friends .. etc.
Will headers
make a difference in exhaust note? Yes they will !! The power
gain will be SOTP (Seat Of The Pants), and the exhaust tone will be louder also
(good thing according to most people !) You will also notice a 'difference' in
the wallet as coated headers dont come cheap and the installation is even
more expensive !! Doing it yourself is of course possible but proves to be far
from easy and can easily take 6-8 hours !! According to the Do it
yourself guys its well worth the couple of hours (and $$$) and the
gains make up for the PITA installation !! They do NOT recommend this for those
who are mechanicly challenged. Make sure you get a good set of
headers cause several 3.8 people suffered from ill fitting headers and annoying
leaks after installation. The Pacesetter headers for the 3.4 work pretty good !
They are a pain to install and with DOUBLE gaskets you'll keep this set from
leaking. Tim Legros has had them on his car for over 2 years now and he has NO
problems at all, No rusting through either even though they are NOT coated ..
Not bad for $165 !!!!
Why get
coated headers, what's the difference? Some headers are coated
for 2 reasons: 1. Protect them from getting rusty, so they will keep
looking good ! 2. To keep the heat inside the headers, thus preventing the
engine bay from getting hot.. Well, the vanity option is just for the
purists as you cant see the damn things anyway ! Coated headers do cost a
pretty more than the regular ones. It might be wise to check on how much a
powder coating costs and save some money this way.
