7900 and 7910

[fordf150]

6400 cat muffler loses 9oz. Never weighed the slr chamber but don't think it's more than a couple ounces.

I personally think my 7910 has more torque than my old 7900.
The weight difference I never noticed. But I do like the sound of the 7910. Reminds me of an 80cc dirt bike. Although the pitch is just right I can't stand to run it without earplugs.

I run my muffler modded Dolmar PS-7900 without earplugs, it's a hypnotizing and addicting sound at WOT under load!
I don't like the idle sound so much though, it is a bit high pitched.
