I would love to see and hear a side by side exhaust comparison. Several 370's with the different hfc's and back or just cat back exhuast systems side by side rev'd upped, launched etc... filmed by the same video camera at the same location, one after another. That video would help those on fence choose which direction they would like to go. IMO anyway.
2 days until a nice big box from FI arrives at my house. I fell off the fence a couple weeks ago. HFC's w/ 18" CF res
