Heatshields with catless headers?

[clawhamm3r]

Personally I wrapped my headers with no heat shield and the temp reduction over the stock setup is unreal.

As for the oil dripping on it and some sort of spark. I could see this being some kind of issue if the exhaust wrap wasn’t heat resistant as is. This would make me to believe these are highly flame resistant as well. I imagine if I took the time to reinstall my old heat shield with the wrap that engine bay would be extremely cool.

If you haven’t wrapped yours I would def look into doing it, made engine bay temps way cooler. More like stepping into the warm sun rather than a brick oven when opening the hood.

To be fair, I'm not wrapped and no heatshield over the header and not like a brick oven either. Going catless makes a huge difference in underhood temps. Unless you ran unwrapped catless first and then took then off and wrapped them, I think you're noticing the cat delete and not the wrap.

Yea I was actually thinking about this during the day today. I figure the cats would collect a whole lot of heat in there. If it wasn’t such a pain to do and I do I would love to do a true effective test with it.
