"For those of you, like myself, who were wondering whether to buy a 44 or go with the 40, get the 44. Its deeper, louder, no annoying cab drone, but lord have mercy if you roll down that window because this bad boy sure turns your truck from nice to mean. I switched from a 40 to two true dual 44s, huge difference. Worth every penny." —Nathan W from Lynchburg, VA bought a Flowmaster Super 44 Series Mufflers for a 2004 Dodge Ram.
"I had glass packs added to my 04 Dodge Ram for inexpensive added exhaust sound. I decided to get the dual outlet Delta Force Muffler to make a change. To really see about the torque/hp added and the clean sound.
The glass packs' raspy start was replaced by a real THROATY DEEP sound. Really made it sound like a DODGE TRUCK. Torque gains were noticeable but nothing mind boggling. It was really the deep power sound that gave people walking by, driving by look at what i had going.
MPG gains? = None. I didn't see a change at all. At 55mph at 4300 rpms i was running about 24mpg on the comp, but now it's 21mpg. Other constant rates seemed to differ also.
Overrall though, i love the sound. Interior is not loud, and that's what I want. U can definitely hear it, it's deep but nothiing too much that will give the headaches." —Andrew R from Saginaw, MI bought a Flowmaster 40 Series Delta Flow Mufflers for a 2004 Dodge Ram.
