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.

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.
