Header Regrets
A friend of mine put TPIS headers on his car. He said they were long tubes but they did not look it to me. The merge collector did not appear to be back as far as say Lg longtubes. But anyway he said he had to dynamat his car because his tunnell are got so hot he could not wear shorts. Do some headers create more heat than others and does any coating controll the heat. I would like to hear some of your comments.

I have SLP long tube ceramic coated stainless steel headers. They are a real PITA to install but worth the effort. When you remove the factory exhaust manifolds you also lose the heat shields. The long tube headers channel more heat toward the tunnel as well. I installed dynamat sound deadener and LComp to the entire interior of my 2001 convertible to reduce road noise - it is not intended for thermal reductions - and it was worth the effort. I installed an Elite Engineering 1/4" thick ceramic coated and thermal lined aluminum tunnel plate to stiffen the chassis and reduce tunnel heat - it was worth the money and time as it did reduce the tunnel heat a lot.
There are different tricks to making things better on a Vette. The GM factory builds a solid base car but then we - the vast unpaid owners - have to fix it and get the rest of what they botched done correctly. I have fun doing it.

The highest heat area is around the cats. These babies need to be hot to work and since the exhaust flow will slow down once it enters them they will tend to stay hotter than the rest of the exhaust. My car also suffered from heat in the tunnel area with the stock exhaust system making the interior around the tunnel a bit uncomfortable. Ceramic coated headers will keep underhood temperatures down and help a bit. Stainless steel headers also have good heat properties and will help but the real cuprit is the cats. I wound up having the exhaust pipes that go from the manifolds to the rear exhaust ceramic coated (exterior only) and this made a world of difference. I imagine a thicker tunnel plate and putting insulation in the tunnel area would accomplish the same thing without having to pull the carpeting out and install the dynamat stuff. Here's what my exhaust pipe looks like after I had it ceramic coated.
