Hot Tip - Low Cost Performance Exhaust

Hi All,

I just came back from the muffler shop today, and feel the
need to share something I think is pretty cool with the
rest of you. I hope this wll be of help to someone.

As many of you have I am certain - I have been looking at
doing a performance upgrade on the exhaust of my car. I
have a 1991 964 C2 - pretty much stock - but just back
from a major service and tune up, and running like new. I
had been looking at all of the specialty mufflers and even
muffler bypass pipes available out there - and honestly -
was extremely put off by the prices. I mean really - $800
or more for a muffler? And - oh yes - there are TWO of
them of different styles - under there! Or - a bypass pipe
to replace the muffler - for an economical $350! WHAT?
$350 - for a piece of PIPE? OH YES - and I need TWO of
them ALSO! Maybe I am the only one that considers
these prices - ambitious - to say the least. But I knew
there HAD to be a better plan......

Well - gentle readers - there IS!

I have been relieved of a grand total - of $179.00 today.

Yep - that is it. $179.00. Including labor and installation.

And here is what I got for that money.....

First - I have reduced the weight on the back end of my
car - by at LEAST 40 pounds...... Why? Because those
two gawd awful factory mufflers now reside in a box in
my garage - replaced - by a single 12 pound muffler.....

Second - I have picked up - by my seat of the pants best
guess - an honest 15 or 20 horsepower. And you can
feel it - from idle - to 6000 rpm (yes I HAD to try it!)

Third - I have a more healthy exhaust note. Not so loud
as to annoy the neighbors - or attract attention from
pedestrians when I drive by normally. But enough to
grab attention as the needle swings above 4000 rpm.
It sounds GOOD! No - make that - GOOOOOOOOOOD!
(laugh) No vibration. No rattle. Nothing adverse. Just
the standard Porche sound - but about 20% increased
in volume.....

Anyone interested in what I did?

I took it to a guy here in town who does custom and
performance exhausts. And he made a simple switch
for me. He came off the catalytic converter on the
drivers side - with a 90 degree elbow. 2.75 inch if I
remember. Then he installed a MAGNAFLOW muffler
behind the rear bumper - where the longer factory
muffler formerly resided. This MAGNAFLOW is wonderful!
It is 24 inches long - 6 inches thick - and almost precisely
as wide top to bottom as the factory muffler. Just a
little shorter at 24 inches - compared to the factory 30.
And - get this - it is a STRAIGHT THROUGH design. Yep.
Look in the intake port - and you see straight through to
the exhaust port. You can't get much more LOW
RESTRICTION than that one! And the funny thing - is
that it works WELL as a muffler! From the Exhaust side -
he simply made another 90 degree elbow - and VOILA -
instant high performance exhaust.

I have a double wall - low heat transfer - tip coming in
on Friday to finish it all off..... I am tired of the paint
peeling around the tip on the rear bumper......

ANYWAY....

This exhaust - works - GREAT! I am serious! It is
surprising how well it actually works! And sounds!

It would be wonderful if somebody - like maybe Pelican
Parts - could check this out - and offer a kit including the
90 degree bends - a decent tip - and - oh yes - an extra
custom hangar necessary - to people here. I think it
would gain quite a bit of interest once the word got out.

Anyway - I am done with the friendly tip of the day. I
hope this is of help to someone.

Remember - these are cars - meant to have fun in!
