Noise after hurst shifter install
I recently installed a hurst shifter and aftermarket **** in my manual car. It seems like transmission sounds carry into the car through the shifter much more than the stock one did. I don't even remember sounds with the stock shifter. Has anyone else had this problem?
Will it go away once the shifter gets some wear in it? Any sound dampening ideas?
Thanks
Ian

When you bolted in the shifter base, did you use rubber isolator bushings/washers? Did you transfer the plastic from the end of the stock shift rod that goes into to the Hurst?
You can take it back apart to look for any place the shifter comes in contact with the car.
The two places I can think of are where the shifter base is bolted to the car and where the shift rod goes into the shifter linkage.

The stock shifter is rubber isolated which buffets the sounds transmitted into the cabin. The coupe/convertible typically use rubber bushings where the "box" mounts above the torque tube for additional vibration reduction. The C5/Z06 uses metal bushings.
Most after market shifters are solid (billet) construction which tends to amplify the sounds transmitted into the cabin. It's very doubtful the noises will go away with wear. You'll either get used to the noise or accept that it's a fact of the modification.
It's a trade off if you want that precision shifting. This is one reason why many chose the C6/Z06 oem shifter. It's my understanding that the MGW shifter is also quiet, but provides the desired precision shift.
Some have come up with DIY ways to reduce the sounds like adapting the oem rubber isolators or cut in half tennis *****. I wouldn't accept that personally. When I was trying to decide on an after market shifter, I chose the B&M "Sport" shifter because of the rubber isolation. I get no cabin noise despite the fact that the "box" is mounted with metal bushings.

It is only noticable when the engine is at idle or easy acceleration with the radio off. Any other time it can't be heard over music or exhaust. I drive with my hand or wrist resting on the **** which cancels the sounds as well. I will try DIY mods to completely silence it or possibly swap the shifter if it ever gets to where I have to have silence. Not too bad for now though. At least it is normal.

That noise is typical with hurst shifters. Best remedy is to wrap alot of teflon tape on the threads where the shifter **** goes. That will silence it. I did that same fix on mine and it worked!

Thanks. I was considering that exact solution when today at work. It seems that even a light touch will stop the sounds.

OK everybody left out the fact that the Hurst shifter uses the stock rubber and requires you to turn it inside out. Afterwards there is a huge gap all around the shifter handle. That allows the sound in to bother you. I went to Ace Hardware and got a big rubber stopper, I can't recall the exact size. I drilled a 1/2 hole in the center and slipped it down the shifter handle and used a wire tie wrap to pull the boot up tight to the rubber stopper. Sound gone. I've read some other fixes using a pvc pipe plug. I'll see if I can find a couple links to threads here.

Been there , done that. It appears that you have a Z06 so you have the shift box with the two solid horizonal mount bushings. This box also transmits slightly more vibration than the C5/ late C6-Z06 rubber bushing shift boxes.
I installed the Hurst C6 3915086 shifter but both ( C5 3195085 ) shifters have bias spring loads to adjust shift arm tension.
