Im thinking about swapping my flows for m80s but Im not 100 percent sold yet. I like the fact that theyre straight throughts and flow wayyy better than my og 40s (ironic huh) but I think Id miss the rumble of the flows. Anyone have a video of this setup? There isnt that many on youtube. I actually run m80s on my 3v but exhausts on the newer cars sound so different than the sn95s, even when you mid mount them. Also would there be any real gains from going to a straight through muffler from a chambered muffler?
