TTI Small Block Shorty Header Install

Looking for experience with TTI tailpipes
I plan on doing same on 1970 Dart Swinger 340,
I want to utilize Factory Tips....are the tailpipes lined up for these tips?
Can I just cut the ends of the tailpipes off and slide in the Tips?
Factory location...using existing frame holes for hangers?
Any help or pics would be great
not sure about alignment, but the 2 1/2" tti pipe is going to need an adapter for a stock tip
