I will be replacing my stock exhaust system on a '72 L24 from the y-pipe back with 2 1/4 inch pipe omitting the resonator. I have looked at past posts regarding new exhaust systems and this sounds like a good way to go. My question has to do with what muffler to buy. I think a turbo muffler is what I want. My choices are a Walker super turbo or a standard turbo. My goal is a nice growl but not obnoxiously loud. Is there a significant difference between these two mufflers other than the Walker's stainless steel interior and warrentee?

My dad just had a Magnaflow muffler installed on our '71 240z. It has a nice sound that is noticeable, but not loud. i wouldn't describe it as a growl, though. We are really pleased with it and we had similar desires for sound, i.e. not obnoxiously loud, yet good sounding.

I also have the magnaflow muffler on my 71 with L28, header, 2.5 exhaust. Sounds good not too loud since I removed the triple webers & put on the su's
