He's talking about Muzzy's full system, which includes the header, not just the mufflers. It's pretty well documented that a full system upgrade on these bikes will give 10% or more HP gain.
That, I would believe. But there is no gain from just changing the C-14 muffler/silencer (which LOTS of people seem to believe). Now that I re-read what ZG originally said and then replied to, I see your point...
"I'll take Muzzys
full dual system over [...]"
My bad.
