Well was on my way back from a service call this am , remembered about another company we do work with and they have a D8R ! So I stopped over there and looked down he’s stack , wide open in the middle can see the Venturi tube clear as day , also the dimples are about quarter of the size of what’s on our stack !i knew my wasn’t right but wow ! No wonder I have so much back pressure
