Down pipes from HO exhaust manifolds
I am installing a 455 in my '76 GTO. It will be using the Parts Place 2.25" exit HO manifolds ( Ames sells a 2.5" version but they were on backorder. I want to run 2.5" downpipes all the way back to the mufflers. Will there be a problem mating the 2.5" downpipes to the 2,25 HO manifolds or will I need to stay with 2.25 pipes all the way back?
