My educated guess is a difference in alloy's in the stainless as to why such a huge difference. probably has allot to do with where the raw materials were sourced and if from 2 different mills or different specs(I tend to think is the case) the tail pipe/tube is probably ordered and then polished where as the can of the muffler probably comes #7 finish and then after welding that assembly is probably electro polished which will slow the coloring process as is closes the pours of the metal chemically
