Well I would say as long as the plastic and the exhaust piping do not touch...You will be fine ...It should be safe, I mean, Honda does put there catalytic converters in the engine bay. I know for a fact that catalytic converters reach temperatures of over 800 Farenheit (just to get ''lit off'')

No fires on the Del (butt ugly) Slow. On the VX I will soon be working on one and am considering the aluminum flashing and tape route that basjoos used. As an experiment, I tried to burn some coroplast with a lighter. It did catch fire but burned itself out fairly quickly. The stuff just melts and isn't really that volitile. I suggest that you try to light it on fire and observe. You may get some idea what would happen.
That being said, Im not sure that my exhaust woiuld get hot enough to ignite coroplast. The cat is on the EM and far away from where the coroplast would be. I keep forgetting to check the exhaust pipe temp when pulling into the garage after the drive home. I have an IR thermometer for that.
Using an IR thermometer, I've recorded readings no higher than 169 degrees F on the portion of the exhaust shown (hangs lowest at the front of my car just aft of the cat).
Eventually I'll get around to putting a scrap piece of coroplast up against it after a long trip to see what the effects are. I'm wondering of a strip of exhaust wrap would do the trick and allow the coroplast to snug up against it?
That is great info. Coroplast won't burn at 169F, I'm quite sure about that. The exhaust tape sounds like a good idea. If you decide to do that let me know if that drops the temp further. I plan on installing my pan this week. Maybe I will go out and get some of that tape.
My thermo-tec exhaust wrap came in the mail on Friday - bummer the package didn't contain the needed exhaust clamps to keep it in place... I should have it installed later this week and I'll take photos and post up when done.
kdb - I took a temperature reading this morning when I got back from work and it was 191F (the highest reading I've ever noted). Weird that it was so high with ambient temps in the low 70's
At any rate, I'll be sure to post temp readings once it's installed!
