Review TWM Short Throw Shifter (STS) and Z1 Transmission Mount
As I get older I am finding that my tolerance for NVH as not nearly as high as it used to be. I think the trans mount NVH also has a lot to do with the exhaust you have. With my Stillen exhaust it was only slightly louder with the trans mount. I honestly cannot tell any difference with the trans mount now. I think if you had stock exhaust and a stock suspension it might feel a little harsh or loud.

Maybe it's the frequency of the noise, IDK.....
Noise is too much. And there is terrible vibration around 2000 rpm when lugging the engine.
I cut through a residential neighborhood on my commute. In order to discourage that, it's littered with speed humps. I generally just leave it in 2nd the whole time, but it's obnoxiously loud. If I shift to 3rd, I have to downshift for every speed bump or else the revs get too low and the car vibrated like crazy.
I'm on the highway for 1 exit, 4 miles. Usually I'm in 5th at right under 4000. Again, it's just obnoxious.
Maybe it's the conditions I drive in and my driving style

I loved the tightness, but the noise was too much for me.
Glorified muffler delete.

IDK, you and Rochester seem to be in the minority. But yeah, I think a lot is my driving style. My average shift point is probably 6000 rpm
It's all good

Sweet! I'm looking forward to that, whatever happens.
Sometimes if I let the engine pull down from very high rev in 2nd or 3rd gear, without any throttle, there is a massive resonance because of the transmission mount. It's pretty shocking. Like nothing I've ever heard before in a car.
I know I referred to this observation when I first got the mount installed. However, it's a rare thing, and became less common (or less noticeable) as the weeks ticked by. By rare, I mean it's been weeks since I heard & felt it last.
If this is what you're experiencing, and it's a regularly recurring event, then heck yes I'd ditch the mount too. And if speedbumps are making you roll through a neighborhood at 6000k RPM with the engine in full load on decel in 2nd gear... well, there it is.

Shifting to 3rd is certainly an option. But then I need to downshift to second--or first, for one of two stop signs. And I can't lug the engine down, or it resonates through the whole car.
It's the same thing on the expressway. I'm not on long enough to be cruising, I'm just keeping up with traffic, where the speed limit is 70 and traffic is moving at 80 and I leave the car in 5th. You know, because 4th is so much closer should the need arise to pass slower moving traffic

4DRZ is right. I need a new route.
