Re: Flowmaster vs. Dynomax Recomendations??
I used to run the Dynomax super turbo mufflers with 2 1/2" inlet/outlet and dumps before the rear end when I drove on the street, but now is a strip only car with open headers. They would resonate bad enough that I would set off car alarms just idleing by. I found that they were also very restrictive, if I made a pass with the exhaust on then made a pass with the exhaust opened up I would pick up aleast 4/10ths of a second which i figure is approx a 50hp gain, and that is on a mild 406 that only runs mid 12's. If I had to do it all over again I wouldn't choose the Dynomax super turbo mufflers.
