"I ordered the Magnaflow exhaust strictly for what it could give me in terms of fuel economy. My Durango was getting approximately 17 MPGs before installation, I am now getting 20+ MPGs! The noise level went up a little in the cab, but it isn't too intrusive. Power increased noticeably after installation." —Frank H from Lehi, UT bought a Magnaflow Exhaust Systems for a 2004 Dodge Durango.
"Sounds great! Runs great! I did notice a little loss in low end power though. But I didn't get it for the power increase, I got it to increase gas economy. And boy has it done the job. Using 89 octane, I went from 13 to 15.5-16 MPG in city, and easily 21 MPG hiway. These days to me that's more important than power." —Joshua H from Mableton, GA bought a Flowmaster Exhaust Systems for a 2004 Dodge Durango.
"The JBA exhaust took me about an hour to install. The installation was pretty simple. I did take it to the local exhaust shop after installation to do some finishing touches to it that was difficult to do while I was on my back. The shipping was fairly quick and the price was unbeatable. Believe me, I checked. Great product, great price and great sound! Two thumbs up!" —Duane W from Shelby, OH bought a JBA Performance Exhaust for a 2004 Dodge Durango, 5.7L V8.
"dont get me wrong it is good for the price but if you are looking for serious head turning rumble just wait till you can afford a serious rumbler as for looks it is clean and i get enough rumble to make me "feel" like its turning heads + i heard it is not as annoying in the cab as the true "rumblers" also I did not get much on gas economy or performance to make me realize but the numbers show a rise!!" —Salvador A from Livingston, CA bought a Gibson Exhaust Systems for a 2004 Dodge Durango.
"I have this and a cold air intake on my truck and they sound great. Not too loud unless you step on it. You always hear it a little bit, but it's not overwhelming. There is a drone when I accelerate and keep it right around 2800rpm's, but if I go either side of that speed by about 200 rpm there is little to no drone. Going down the interstate in OD anywhere between 55mph and 85mph, it is mellow and fairly quiet. I may have gained 1mpg, but it's hard to tell since I am still enjoying the sound too much at this point." —Joseph C from Oxford, OH bought a Magnaflow Exhaust Systems for a 2004 Dodge Durango.
