I think you're right, that the motor mounts are relatively light on NVH. Certainly when compared to Z1's poly transmission mount. With hindsight, I should have done the motor mounts first. There are moments when I think of going back to the stock transmission mount. It's been a few years, and I've been wondering if I'd like less rumble through the floorboards. I think my OEM mount is still up in the attic.
Given that the OP already upgraded his transmission mount, then yes, he really won't see much of a change in NVH.
Here's an old pic, with the OEM shifter, too. Panda, if you still have it, I'd say hang on to your OEM mount, just in case.

I don't mind the vibrations. I remember reading somewhere that the mount can be spaced out in a certain way to lessen the NVH. The information was stated by someone at Z1. I'll try to dig it up and try it then report back.
Shawn made this exhaust at my request. It’s a 3.5” single exit exhaust with a vibrant resonator and helmholtz chamber. Totally weight came out to 27lbs.
my ideal for this was mainly preparation for when I go boost. I know 3” have worked but wanted to see how things would be if I had something in between a single 3” and a dual 3”.

They sure did polish the heck out of those pieces.
Looks like a Meisterschaft component, the way bends are stepped into with incremental pieces in the curve. There's probably a welding term for that.
Anyway, it's pretty. Not really into burnt Ti tips, particularly if the burn is competing for space with the logo, but can't deny they look nice. And don't know what to think of the flat cap Helmholtz chamber. I'm curious to see what that looks like on the car.
FINALLY! I just received my parts from Rej at Rabbit Hole Motorsports. It took a while as he had to redesign a few things, which is understandable. I am still waiting for the throttle bodies to be shipped to me as the final pieces.
As soon as I have these parts on, I'll be pulling off my EPS and CFM Performance ported upper and lower manifolds. Probably going to want to sell those items together as it was ported together.
In terms of gain, I'm honestly not looking/expecting much if any gains. Matt had a set on his car that didn't produce any gains. I mean, there's only so much air that can flow in N/A form, especially since I'm not built/stroked or anything. As long as I don't loose any power, mid or peak, I'm good. I plan is that this will help when I go boost.
Hey Bull, I definitely will do. I am hoping I'll get my car back sometime next week from the body shop.

I'm a fan of Shawn's work, though I don't know much about welding. I really liked his original 3" super single he made for the sedan, so I asked him for this. I do feel there is a lot going on at the tip. I slightly feel I should have gone with a more subtle style. but its ok. The helmholtz he had on his original single helped a ton with the rasp vs those that didn't have it. We'll see how this will sound, considering this is also a 3.5"
