If noise is a primary concern, the GMM street version is probably your best choice. This option retains the factory lever which incorporates a rubber center section for noise/NVH isolation and damping. All of the other shifter options do away with this damper thus allowing more NVH into the cabin. In some cases the noise can be quite loud, it varies between shifters and also depends on your particular transmission as some are inherently more noisy than others. There have been people who installed the GMM race version, which is basically a metal rod right into the transmission, and reported minimal noise. Others with the same shifter stated the noise was unbearable and some even swapped the lever for the street option.whats quieter, billet or gmm or are they about the same, or matter of opinion???
I got my GMM street from JHP, here's a link :-Can you tell me which vendor that I can get the GMM shifter and the LSS knob from?
I love the Billet, but I think the break in period should be listed as a con. It took me at least 500 miles before I saw a hint of loosening. And it was exceptionally tight. I drove it exclusively for a week, than drove another car with a stock manual and almost ripped the shifter right out of the transmission...lol.Stock(sloppy), then went B&M (always leaked then broke), then Hurst with stock knob(noisy, reverse was out in right field, entire pattern seemed very wide, more positive than the B&M), now Billet. Billet is expensive, and requires more effort to install but well worth it. Was stiff at first then loosened. Adjustable throw(shaft has 3 mounting positions). I started with middle then went to shortest throw. Never missed a shift cause of the shifter. Never tried the GMM but I rate the Billet well above the others I have had in my goat.
