Only because i have poly everything. At least thats my assumption. It doesn't bother me any. I'll accept nvh, as long as it rips, and stays a nasty 40 roll car. But my preference is different than most lol.
Honestly i can't give you an definitive answer on that. I did my poly mounts at the same time i believe. Sorry i cant be of much help on that. But definitely added overall. I think its because its solid mounted, and travels through the linkage, and the old had rubber on the factory shift arm for the trans and body. And plastic bushing for the shifter ball cup thing.
