So I just bought a G37S muffler, I do know that the tips are going to stick out by 2 inches or less, so it's eventually going to get cut/re-welded.. Rumor has it that the stock 370z pipes aren't the greatest as far as sound goes. Problem is, I don't know how the whole system works..
So air goes into engine via intake to the engine > headers > catalytic converters > mid pipe/y pipe (wait, hold on, is y-pipe a midpipe?) > mufflers?
Either way, my plan is to get the g37 exhaust and swap out the midpipe section with some other brand.
aiming for this noise:
