4X HEMI... I understand that magnaflow might actually flow better but I love the way flowmaster sounds, and from what I hear a small amount of back pressure on my MDS HEMI is a good thing. and Ram0447.... I'm a VoIP Network Engineer... I fix and install carrier-grade network equipment so things like your comcast digital voice or verizon iptv works... and chongo.... i'm trying to stay away from headers because they are quite often a royal pain in the *** and the truck is still a baby... but someday I'm sure they will be on the list

 

Actually the Magnaflow sounds just as good if not better then the Flowmaster plus it is a true performance muffler. Some of them can be just a little bit quieter on idles but when you open them up, they scream. You want loud, then you get a smaller muffler, thats what makes the difference. I use to have FM on my truck, I changed everything over to Magnaflow and I can not believe the difference it made.
Nothing wrong with some Headers since you like it loud, you will truly open up some more power out of that engine.

 

I have heard good things about the edge and want one myself.

 

Ok, I decided since I already did exhaust (although it is not really what i want) and it seemed to be the popular vote I'd go with the programmer. I ordered the Edge, and I'm picking it up Monday!
