What does the “resonator” do before the muffler, never seen that in parallel to main pipe

In a nutshell... it cancels drone and makes for a much smoother "performance" sound. Magnaflow and Borla are known for this design. Been around for several years.

This is a split backflow design. Reduced rumble with all the performance flow.

Magnaflow and Borla have write ups and vids of this.

The resonator does not tie directly into the muffler. It is "looped" prior to the muffler.

Very interesting, thanks.
