I'm thinking this depends on how much you drive it...

I just know a bit about rapid expansion and compression of the gasses. I've noticed that after just a week the glass pack has mellowed out some....I still detest the sound of the glasspack though. Acceleration also seems to have been reduced over stock
I only put about 3000 miles a year on the VX.

As far as I recall...it took about 3 months to mellow, and that included a drive of 1800 miles to Moab and back.

So..maybe 2000-2500 miles and it was good.
But thats all very subjective ....noise wise!
