RE: [DML] Performance Muffler



Rod, From what I have dealt with over the years in dealing with corvettes is
the best muffler you can put on the car with the headers for optimum
performance would be a Turbo Muffler. The one you are talking about could be
built by anyone and I'm sure would be some form of no resistance turbo
muffler. I'm using at this point on my headers is the SS polished turbo
muffler. Magnaflow also makes a rear mounted dual in dual out like our
muffler no but it classed as a turbo muffler because of the least
resistance. 
To me any time you try to muffle or restrict to control the sound then you
would be limiting the HP that you're trying to produce. So the problem is
how much do you want to muffle the exhaust to produce the sound. I can adapt
most any muffler that a customer needs.

Subject: [DML] Performance Muffler

Shortly after purchasing my first DeLorean(6032) in 1999, I bought a
"performance" muffler listed on Ebay. The impulse purchase has occupied
space in my garage for close to 10 years since I traded 6032 for a
DMC(Texas) Refurbished DeLorean in 2001. I am confident that the muffler was
one marketed by DeLorean Specialties in Philadelphia in the late 80's, early
90's. DeLorean Specialties was operated by Fred Lockett. Delorean World
Volume 6 Number 4 Summer 1989 has an article by Fred which describes the
muffler and the installation procedures. The 304 stainless muffler has 2.25"
exhaust tips cut on an angle.The article says the free flow design "enhances
overall performance and fuel economy, liberates a powerful engine sound".
The muffler was designed by Borla and a 15% horsepower gain is claimed. The
Ebay seller stated that the muffler was purchased at P J Grady, used for 600
miles and then removed from the car. In looking at the muffler it is obvious
 that it has been installed but used very little. I would be interested in
hearing from anyone that has had experience with these mufflers. I have
heard from one source that they were too loud especially on a long trip. I
am considering installing it on my car but would like to hear from those who
may have had experience with it first. Thanks,  Rod VIN 10921
