Hey Tony,

That coating did look very clean! Question......did you or your installer use silicone sealant when doing your installation?

I have done a few installs recently and have not used "RED" silicone which on GM cars(and there is a SB out to GM dealers about it and it happened on my own C-5 when I installed headers)will trash the O2 sensor. The last viper I did, a 01' has yet to get a check engine light and has around 1000 miles since complete installation.

Just a theory based upon factual information from other cars. BTW when I removed the headers from my own vette(99 C-5) cleaned off the red silicone, reinstalled them, the light never came back on.!!???

Just my $ .02

I have a standard set of Belanger headers & catbacks as well as bullet cats on my 2000 RT/10. 3,500 miles and NO CE light (knocking on wood now)!!!
