Hi Reggie I installed the Bellanger headers for the sound not for the extra power and eliminated the cross over pipes and add the high flow cats and Atro racing exhaust.I've never had the powder coating chip peel or come off,it looks like the day I put them on.As for the heat Atro Racing heat wraped my side pipes which kept my sill cooler .I aslo did a computor chip upgrade by DC performance which came with a 180 degree thermostate which also keep engine cooler.I did these mods so I didn't have to put the heat shields back on.I haven't had any heat related problems. Personelly I like the modification it made to my car.It will make your car sound louder,which I wanted ( It got rid of the UPS truck sound out of my car ).Just for the record,everytime I go to the Viper days at the race track People come up to me and say I have the best sounding car out on the track.And that is what I wanted .I hope this helps.
