Gotta find me some late model pipes I can introduce my grinder to. Haven't done a good dissection since high school.

Looks like the earlier pipes were a 2 stage pipe with the disk in there. The later pipes were supposed to be better but they look straight through. Am I missing something?

Thanks guys.

I edited my post and included bigger pictures of the dyno reports.
Due to forum rules on posting pics, the graphs were a bit small and hard to read.
