4Nice muffler
By AKShawn
Like most of my Amazon orders; I recieved this order ahead of time and in good shape. My truck does have a better sound now. Sounds good and not too loud from idle to about 2500 RPM. When you step on it; It sounds REALLY good! Not sure that I am getting more performace as I have only had it installed for about a week now. Seat of the pants...maybe some. I do hope I get some MPG benefit by vertue of less restriction and a new K&N air filter. That has not been the case in town according to the trucks computer. Probably because I have had my foot in it more just to hear that Hemi go! Overall, I am happy with it.

5Perfect for the job
By Hahnz
The Dynomax website gave me all the information I needed to make a decision. It even gave me an idea of what the muffler will sound like. Muffler is quiet at idle which is what you would like to see but when you start moving, there is a nice, not menacing, rumble. As for the muffler's ability to help my mileage, I hope it does but I am not expecting to notice it. First off, on an older truck, a '03 Dodge Ram 2500 with 186K miles, I may not even see it. Because of the muffler design, however, I do believe that I get better performance. There seems to be a little bit more pep in the old girl these days.
