woah... i didn't even see #4 back there till you mentioned it. wonder if it has anything to do with the fact that the other pipes are not close to it and thus there's no radiant heat to keep all of it's heat from dissipating?Cool pic...and a couple of observations/questions.
Why the Chev bowtie?
Check out how much cooler #4 is running than the front three pipes...weird.
