Before I had installed the HFC I had vibrant 1792 resonators in place to control the raspy exhaust and quiet things down a little overall. Now with the HFC in its place now, the sound is the same or a little louder it seems and the rasp is a little worse but not bad at all. I'm happy with the exhaust sound.
That's nice! thanks for letting us know.
I'm assuming from your signature that this is VRSF 200 cell HFC
