It all started with a bunch of pipes and a challenge to build a set of tri- y headers for 360 65 Barracuda ( since nobody makes them ) haha since my shoulder was rebuilt ( been a year)it is finally time to get it done, been in the garage looking at parts for the year. Have the top part mock up to the first set of ys , now for the 2 inch pipes. Here is the question is there a special length they have to be to the next y ? Have to add primary’s are 1 5/8” to 2” to 2 1/2” exhaust . So far 50 bucks and 6 hours and no room for anything haha , the two photos of Chrome is the pattern of thought I,m using.
