I have a single Magnaflow with dual 3" in and 3" outs. I love the sound of mine, especially around 5000+ RPM.

I don't think mine has the built in crossover, just common air mixing chambers.

well ,theyre definately Loud as hell.at idle alittle quieter than the dynos ,but the second you get into it it sounnds like the old hot rod glasspacks,or cherry bobms.im definately happy not about paying $200 + for mufflers to quiet my truck down and it getting louder.dont mean to jack your thread but i thought you would want to know.any suggestions on how to quiet it down now.im thinking add another muffler toward the back by the bumper so i dont get the crackle.
