Greetings, we have been doing a lot of muffler testing since about 1988 on big Pontiacs and our 340-360 cars. Also, I have been playing with vacuum operated mufflers which are not meant to be race pieces but are great for those wanting a dead stock sound on the way to a show but want to be able to make Flowmaster noise levels once you get there.
If anyone is interested in seeing some data or learning about the mufflers, be glad to post some. Otherwise, thanks for the site and for the opportunity to be able to read about others' work and experiences.
