yeah those look like they would work better.. I'm fairly certain the OEM are almost identical to the Nameless mounts.
5" muffler/4" tips
**EDIT*** to answer the question how do I like them.
I like them better than the muffler delete, that was pretty obnoxious. They don't drone, but you can always hear them if you know what I mean. it's not that inner ear constant irritant, just that you know they are there. Turn the radio on and they are mostly forgotten.
the look is nice, the 4" tips fill out the opening nicely too as you can see above.
all in all I'm happy with the purchase.
