A muffler is a muffler, despite the branding. Seen plenty of domestics with "import only" mufflers.
I had a Flowmaster 40 Series Delta on my F22B2 and it didn't sound bad. I went from a Cherry Bomb glass pack to that and the sound was just as loud, but refined into something a bit more respectable. For $80, it was decent sounding, dual outlet with stainless tips. Nobody was the wiser it wasn't Greddy or Apex'i.
You really can't get too beefy of a sound out of the F23 if you are keeping it legal. Keep looking thru videos of 4-cyl accords, and see what they have. You CANNOT compare a v6 or even another 4cyl car to your own, to try and see what it will sound like.
