Hi

My stage 2 GTS is quite loud from the inside. The GTS has noise insulation parts stripped as opposed to a normal Carrera. Is it possible to reinsulate the noise insulation part into the car? Has anyone ever done this?


Cheers

Yes... a few people have done it (myself including) on a 991 GT3. This is only one of the threads: GT3 DIY sound insulation - Rennlist - Porsche Discussion Forums
It's fairly easy... just time consuming. Took me about 4-5hrs, but I did the doors as well.

I got some Noico to do just this. But haven't gotten around to it and I've grown accustomed to the 'loudness'

How do you get around removing the interior panel? What tool did you use? Any warning?

Stark7x

Honestly, they all just pop out. I just used my trim removal tool to get under... The only thing that has a screw is the rear middle panel (on my GT3) since we don't have rear seats.
Just do a google search, there are so many videos and posts out there.

Door panels are easy too, 4 plastic panels that pop out and then 4 screws... then the door panel just lifts up.

Thanks for the reply

Correct me if I am wrong. Does the insulation tape only go to the rear seat/storage area and the doors? Did you remove the seat prior to installing the tapes?

How about the footwell? Under the seats? How thick did you do?

Do GTS models (particularly 991.1's) have insulation removed? I thought that was just on GT3's.

I bought the ones from Amazon... they are referenced in one of the posts. I did a 2 part, like a few members in that thread i posted. I had to unbolt my seat and move it forward in order to get in the back. My GT3 has a roll cage so it's harder. I did, pretty much, everything from the back, where your seats would go, to the rear trunk area. Didn't do anything under the seats or in the drivers area as the engine/exhaust noise is in the back area. The doors helped with some of the wind noise and it made the stereo sound much better, in all honesty.

If its motor noise plug the sound hole.

No it is the same as the base cars but there was another sound reduction option at one point. Not sure if it was glass or actual insulation.

I thought “Ts” were the only ones (outside of true GT cars) with less sound insulation...

Where do you find the sound hole?
