MagnaFlow Exhaust Flowbench Test: Does a Quiet Muffler Impact Airflow Performance?

It seems logical that a larger, quieter muffler will have more of an airflow restriction than a smaller pass-through design. But as it turns out—that’s not always the case. And to prove it, we travelled to MagnaFlow headquarters to do some side-by-side flowbench muffler comparisons. Suffice it to say, the results may surprise you. So if you’ve ever wanted a quiet, free-flowing muffler without the noise of a traditional pass-through design, then you’ll definitely want to watch this one.
