I highly recommend a Pro 5.0 shifter with a MGW Shifter handle http://www.mgwltd.com ...
MGW is supposed to be making a SHIFTER so you might want to wait on that. Just changing your stock handle to the MGW handle will make a HUGE difference.
Thanks Abe. I actually read that thread again just a few minutes ago and figured that was the one you were referring to. That's a problem I haven't heard before. I had two TriAxs installed on my Cobra and they were both fine. I got rid of the first one because for some strange reason it was SUPER loud. So I sold it and bought another one, which was quieter but still just a bit noisy. A few months later I started making my shifter gaskets, installed one (of course!) and the noise pretty much disappeared.
