im faced with a dilemma. want to go with magna flow. ive had their systems on my old bronco and chevy 2 door tahoe. but i've only ever bought just the mufflers. so I'm wondering, whats the main advantage to spending $1500 on the magnaflow catback system as opposed to just buying the mufflers for my 08 G35?

 

exact match on pipe diameter throughout? i'm not sure about the magnaflow and the g with the hr motors, but true dual? muffler xchange will be just for sound purposes and aesthetics. not sure if you'll really have much, if any power gains. and it really won't sound like what magnaflow designs it to be. does magnaflow still make a full catback for G's? sorry i think i'm asking more questions than answering yours lol. try looking at other brands for our cars. lots of choices for japanese cars
