Default Ceramic Coating X-Pipe for Tunnel Heat reduction

I haven't tried it yet but looking into the upgraded tunnel plates with ceramic and heat insulating layers ...Thinking maybe i should pull carpet up and insulate, maybe I should get the ceramic coated 3/8th plate and then add the heat insulation to it on top of whats there. Made me wonder if I shouldn't just have the X-pipe ceramic coated, if the X-pipe is gonna come off anyway and save the expense of the heat layers on the tunnel plate and just get a stiff one.

Thoughts? Anyone have this coated and eliminate the heat in the tunnel problems this way?

Ever since going to headers and high flow cats I don't even notice the tunnel heat anymore.

I bought mine with longtubes and x-pipe and also don't notice any tunnel heat. That said, when I had my 2nd C4, tunnel heat was extreme. I solved it by having the tunnel lined with some expensive heat reflective self-adhesive mat during the trans replacement.

I installed one of these when I went with the long tube headers and x pipe. Heat is almost all gone even on the hottest days.

2009 C6Z, OE manifolds/cats, aftermarket X-pipe (replaced OE H-pipe)...I installed a ceramic coated tunnel plate with thermal insulation, and I even installed a thermal "heat blanket" up in the tunnel. Definite reduction in center console heat, but by no means is the heat "gone"....the interior/console area still will get heat soaked if driven long enough. I wish I had ceramic coated my X-pipe prior to installing. Had a great local coating company back in Orange County...I just had a brain fart on doing that before installing. If its coming off the car, I would most definitely do it...it certainly wont hurt anything, its only going to help.

I did the aluminum covered bubble wrap insulation under the carpet nearly 10 years ago. Not only did it cure the heat, but reduced the road noise. I've helped several friends do their cars with similar results.

Ditto on that, plus now they have pieces that go up the side, do it, for the money and ease of install I don't think any thing else would be much better, JMHO

I'm sure all these help, doing more than one should be even more effective.

This is for a C5 but the C6 kit is very similar.

I forgot to mention that this is a 4 piece kit that includes the side shields with the center plate cover. All custom cut for easy peel and stick application.

I insulated the tunnel plate and sides several years ago on my 2011 GS. I just used 1/2" foil covered generic insulation and it worked great. But it does not eliminate 100% of the heat. A significant amount of heat is transmitted down the torque tube and finds its way into the cabin. Some additional insulation under the console and carpet is worth the extra effort.

Check out our Under Carpet Lite material. It is an excellent heat and sound barrier and will triple as a carpet padding. If you need something a little thinner check out our D-Mat material. Again, it is a great heat blocker, will absorb some sound and is thinner and will compress down to closer to 3/16". You can see them both at the links provided. http://designengineering.com/under-c...on-insulation/ and http://designengineering.com/d-mat/ . Let me know if you have any questions.

Thanks, Tim
