Project Valve Technology Muffler
well i ended up selling my JunB.L and i ordered a HKS sport catback from lancershop. i wanted to order from Map but they were sold out 
i must say that the HKS sounds a little louder than stock during idle but not by much. during cruise it is quiet, i would say just about the same as a stock catback which i installed after selling my JunB.L and waiting for the HKS top arrive. my car has a Megan 3" Dp and resonated TP. i can actually have a conversation on my bluetooth radio without issues and the car sounds good, not as good as my JunB.L but good enough. im sure it will hender performance a little compared to my JunB.L but if and when i feel it becomes a "bottleneck" i'll add the boost activated cutout prior to the muffler. for now i'm happy!
heres the thread i have on it

Comparison to double magnaflow is night and day. The double magnaflow is not obnoxiously loud, but it is not stock quiet. Vt muffler offers the stock quietness that I seek.
The Varex muffler is manual operative. A lot of us dislike having to have to push a button for it to open then push it again to close. We prefer something instantaneous controlled by throttle or boost.
Well to update. My VT muffler after a year now, has started to rattle a little during start up and sometimes from a slow initial take off from a dead stop. I think what I will do now is make 3" exhaust setup and integrate it to an OEM muffler and then use a boost activated cutout right behind the oem muffler. Similar to or most likely exactly how a member here did it.

I used and canned this . Clanky sounding rattle would never totally disappear. Bent it here or there but mitigated to a different frequency that's all.
Now on hks sport. Louder at all ranges but less annoying.
I'm on s2 cams though stock or lesser cams may fair better.

I just installed it:
Rattles and makes car feel cheap, at 1000-1500rpm.
But cruise it's quiet as stock.
Tre concept works, the execution is poor.
Therefor I plan to make my own.
If/when I do I'll report if results are good.
The sound out if the Dynomax VT is "cheap",
My JIC exhaust sounds great but a but too loud: 98-100dB at idle
The Dynomax is 84-85dB
Huge difference but
Not nice sounding and rattling
Not acceptable

Yup some how my active tail silencer was way quiter.
Still have it although probably a bit restrictive for cams / 71 hta.
Stock cams and the fp white was blowing exhausts apart.
