i dont know why this is being asked over and over recently.

Agreed.......

Will the 3" WS2 (no cat, no resonator) be extremely loud? what about @4k highway speeds? Would I be able to talk with passengers? If it is girls that talk too much, I guess I wouldn't mind the loudness. haha
I have a vrs 3inch, with 2.5ssac, and a ws2, with stock cat. If you do any research on this topic (already beaten to death), the stock cat flows pretty good, and cuts noise allot, and (yes none of you probably care) makes our emissions allot less of a contribution to greenhouse gasses.
I find my exhaust to be extremely manageable under 5k. Highway it is still easy for me to talk or listen to music, or whatever. The ws2 is exactly what I wanted. In Maine, they are pretty strict about noise, and I have passed countless cops with no issues what so ever. The ws2 is the quietest muffler I have ever heard on a 3inch, and has one of the deepest notes for a n/a car.
Everyone has their own opinion, but when people ask why the 3inch is better? Because experts have continually proven with dyno charts that a 3inch makes more power and sacrifices no torque on the sr20ve motor. It's that simple, end of story, the constant threads popping up still baffle me.
Lastly, not to be redundant (I have posted this like 50 times in last week because of the constant questions concerning this setup) but here is a quick clip I made for just this question in hopes of helping people. I will make the comment that over 5k i get a raspy noise which I am attributing to not having a resonator and a failing cat. Other then that (if you don't like raspy) I love the setup. Notice how its not very loud inside the car (by my standards) and still manageable with no droning exhaust noise that hurts you ears.
