yes.. MGW is coming out with an 05 product rSN. But - I got tired of waiting. I too had more NVH but I discovered that my adjustment was just too darned close. Take off the rubber boot, open up the set screws another 1mm on both ends. Make sure you have 2mm slop between shifter and stop screw.
Next thing I did, while the whole thing was de-rubbered and the center console off (easier to put rubber boot on with console off - and it's only like 5 screws) was to dynamat the entire area around the shifter. For good measure I wrapped some dynamat around the shifter handle itself. Heck, it's buried under leather, who cares.
After those two things, my sound is almost at stock levels! Give it a whirl folks. I don't imagine the MGW shifter will be much different - after all, the transmission design calls for just this sort of solution (the triax is just like factory just different materials). The reason there is more noise is the same reason that it works better. Stiffer material, tighter integration - and in most cases, installation that's too close.
Good luck!
