Exhaust question

[Oxford14Stang]

Was wanting everyone opinion on the stock resonators and when I say that I mean flow. How restricted are they if at all? I plan on keeping mine on for two reasons. One I have no cats, and no mufflers figured it'd be a good idea to keep the resonators in place. Just let me know what yall think.

Flow probably isn't too bad. I deleted mine and didn't like the sound so I put in some dynomax race bullets and it sounds much better. And I'm sure they flow just fine.
