I love all the advice everyone!!
I know there is no "required" distance and each one can be different. Not all pipes are bent or welded the same. Was just looking for some pipe-to-body distances that anyone that has a CR or even an Excalibur for their setup. If I give it at least a 9/16"of gap to the body, I should be ok. Burning the leg is not the issue, but preserving the body/paint is. I have alternatives for the legs, but not for the car body. LOL
