Exhaust sizing

I tend to agree about the one size all the way through. I am going with a 3" system on the truck when I redo it. Generally, I do not like the system to neck down from whatever the collector is. So, 3" collector gets a 3" exhaust system. Let the arguing begin, but that's my personal preference.....whether the extra size is needed or not. That's just how I like doin it.
