I currently am using the 'Super Turbos' on my '69 big block 'vert. I wanted to ask if anyone had had those on their car and switched over to the 'Ultraflows' I think they are called.
If so, any power gains and are they a lot louder?
I want to get a bit more power and the mufflers may be the cheapest way to do that. I just don't want a real loud & resonant exhaust note. The Super Turbo's are not too loud but I think a little bit louder would sound better.

I have the DynoMax Super Turbos on my 68 BB and agree they are a little on the quiet side but still throaty sounding. I really don't think you will gain any horsepower with the change you are thinking of. If you are looking for more sound go with the FlowMasters.
