Andy: I am not sure if the DMCH's Performance Exhaust uses a Flowmaster muffler..... But according to the picture that they posted, it does looks like one. If it is the Flowmaster muffler, I can tell you that Rob (PJ Grady) and I had them in our cars. He had one in his Green DeLorean and he had it removed and it is now hanging in his inventory room's wall. Rob did replaced with a Borla muffler that cost him some $$$ (don't even ask!) to special order. I had a complete stainless steel system fabricated with a Flowmaster muffler installed in my DeLorean without consulting Rob and I should had consulted with him as to avoid the COSTLY mistake. Anyway, I had the system for a very short period of time, some where of two or three months and I then had the whole system removed and the original system remounted back in my DeLorean by Rob. Anyway, what Rob and I both agree on is that the Flowmaster is too noisy and I myself, I couldn't tolerate the "droning resonance" in cabin that was produced by the Flowmaster muffler during the long drives that I periodically do. I drove back to the fabricator in New Jersey some 60 miles away from NYC as to have them resolve the resonance problem. They call the Flowmaster company and Flowmaster said that there is a "jacket" that could be fitted over their muffler as to dampen some of the noise and resonance. I didn't go with that suggestion due to the issues that there is no room for the jacket to be install between the muffler and the wall of the engine compartment. Besides a jacket will is "ugly" and it will get sloppy in due time..... BTW, I spent over a "G" note on the fabricated pipes with the Flowmaster muffler and it turn out to be a failure. Two years ago, I ordered the British Stainless Steel System and I had Rob install in my DeLorean. (The system is beautifully made and polished. You would like to hang it in your living room as a work of art.) The Stainless System is noisy on acceleration, but without the cabin resonance while cruising or driving. I kind of wished that I gotten the muffler with the "extra packing" as to make the system a little more quieter. FYI, the Stainless System is available in three different packings. Either packing allows more horse power as "pep." Anyway, Rob agree that my Stainless Steel System has slightly more pep then his Green's DeLorean set up but with slightly more noise and my DeLorean has just as much pep as the several DMCH cars that he has come across. In closing and in my opinion, any DeLorean with the OEM exhaust removed and a free flow system installed, a DMCH, a Stainless System or otherwise..... They will give you some more pep .... Real noticeable pep. Now don't start asking me for dyno test as proof....... I hope that helps.

I have heard from others that it may be too noisy for some tastes. Can anyone else comment on this who owns the exhaust? Does it fatigue you on the interstate? I would not have the stage 2 engine - how will an otherwise stock motor's sound be affected if the exhaust was developed to work with stage 2? What other options are currently available? I know there is a set from the UK that is quite expensive but also very good. Anything else?
