Default Those that have changed tunnel plates.....

For those of you that have changed your tunnel plates, would you be willing to sell cheap or maybe donate your OEM plate? I'd like to do a little experimenting and need one to work on.

Does changing to the new plate really noticeably change the temperture around the console, increase stiffness of the car????

Yes it does! The main reason I got it was to reduce the heat inside the cabin.

Rather than "changing" the tunnel plate, I added the aftermarket plate using the factory bolts (i.e. two plates now), so I don't have an original to give up.

Temporarily, in other words for trips of less than 30min, yes. For longer trips, no. Once those cats get really hot it's just a matter of time before they overwhelm any available solution.

I've noticed that drivers, like me, that rest their right leg against the tunnel while they're driving will be most sensitive to tunnel heat. I have noticed that those folks that do not rest their leg against the tunnel wonder what all of the fuss is about. Of the six or seven drivers I've been with I've noticed a positive correlation between seat position and complaints (people that keep their seat relatively far back have few complaints) and, ahem, relative obesity and complaints (skinnier folks seem to sit differently in the seat, and be farther away from the tunnel). Plump people that sit close to the wheel tend to bitch the most, like moi.

I had one of the EE plates installed, but had it done when LT's & HF Cats were installed. Overall it's a good bit hotter than it was stock, but since the plate went on at the same time, I don't have a good comparison as to its effectiveness. Your comment on the time frame is spot on. But here's the kicker for me, by far the hottest spot is further back, right below where the traction control button is. And I'd swear the problem is getting worse (hotter) as time goes on. I guess I'm going to have to get the car on a lift and check that area out, but overall, I'm disappointed with the console heat problem and the after market tunnel plate.

For those who are are still complaining about heat on those long trips, have you guys ever considered Header Wrap??? But instead of putting it around the header, just wrap it around the cat the the piping that effects cabin heat. The idea is to contain the heat in the pipe rather than just block it after it escapes the exhaust system.

It's pretty inexpensive stuff and advertised to handle over 1000 degrees. Do you think it would work? Anyone try this yet?

Sorry about hijacking the thread.

Has anyone ever done a test on the plates? Put a thermometer in the center console and drive for a predetermined amount of time.(30-60min) Then install the plate, let the car cool, and go out again.(even on a different day as long as the air temp was similar) Driving for the same amount of time, on the same course, and with the same driving characteristics. I'd like to see some solid results as far as temp. control.

I was told a few years back that it isn't a good idea to wrap the cats in header wrap, they can reach 1500 degrees F. The best ways to combate the heat issue are to fully coat the headers and all exhaust pipe inside and out with ceramic coating and use the tunnel plate. A really good idea, but rather expensive, is to use a really good heat "reflecting" materail on a "lid" above the cats. Gold is a good reflector to line some so called "lids" with.

This is spot on! I can say that the tunnel plate serves the other purpose well, though, that is too stiffen the ride. I noticed its effect because it quieted some annoying squeek that I had.

Zero sotp effect but still music to my ears.
