if you're concerned about the heat from the pipe (a very justified concern IMHO given the tremendous heat and limited airflow in that area), simply heat wrap the pipe. I did mine for that reason. As I had lots of heat-wrap left, I did both pipes right up to the section where they meet up. In addition to helping control the heat (which surely heats up the oil pan too and contributes excessive heat to an engine that is already "thermally-challenged"), the extra heat staying in the pipe will help exhaust scavenging by keeping the exhaust gases hotter and enhancing flow, netting a very slight performance improvement (will certainly not harm it anyhow)
