Really? I'd think any restriction around there would have seriously detrimental effects on the engine's ability to evacuate heat.
I once stuffed a pair of unwrapped 4" baffles into the tops of my headers, the theory being, fuckit, let's see how that affects the sound and power out of this thing. I made it about a half mile down the road before I noticed the headers were GLOWING. It really must've been an amazing sight for the cars around me. They'd also expanded a good half centimeter. Keep in mind, this is with baffles that have a 1" passage clear through the middle - relatively little restriction. It's truly amazing my head made it through that bit of genius.
