Knows some stuff...
This isn't really a true dual (if that means stays split from the head), but it is kind of a dual with a glasspack at the tips and it is about 8' behind my hi flow cat. I can keep you posted how long it last, so far it is 6k miles and climbing.I am almost tempted to have a true dual exhaust made after the cats and have glasspacks at the tips instead of mufflers. sounded hella good on my tib.
I am still very happy with it though at 2500rpm +/-250 it can drone a bit. I though about maybe getting a resonator in there, but it isn't that bad yet, and it is only in that range which I am not in often enough. I would say the part I like the least is how far the tips stick out, but that isn't too bad either, it just isn't ideal IMO.
