I talked with Ron Olson at Flowmaster to see what mufflers he would recommend for my new 650hp Max Wedge engine in my 1963 Dodge 330 Ramcharger with its 3 inch exhaust system. He said the SUV 50 Series (Pro 50s) would meet my size limitations, noise reduction goals, and provide the maximum power. I purchased two Pro 50s from AutoAnything during their Labor Day sale and had them installed last week. The Pro 50s are fabulous! They met my size limitations, produce a great sound, and allow my engine to run and breathe better. I would recommend these mufflers to anyone with a high horsepower engine,

I had my resonator taken off due to a large dent and hole in it and couldn't stand the hum I would hear in the cab. I didn't realize how important the resonator was. I had this welded on and the cab is back to normal without the noise. I have also noticed a slight increase in fuel mileage / power. If someone says the resonator is not important and you won't notice with it taken off is wrong.
