I have Belanger headers, and removed the shields. True, lots of discussion on the board about it, I read everything I could find on this board on and the Alley. I also talked to several Viper owners too. So, since I removed the shields I decided to add AB high temp wires, and heat socks. I covered a few sensitive parts as well just in case. BTW, I have RT cats and Corsa exhaust. Maybe you can find my post and read it for more info. Three things of interest, first it does run cooler. I had my mechanic do a before and after temperature check. Second, the sound at WOT is amazing. Lastly, it looks awesome. Good luck with your decision.
