I am going 2 to 2 1/8 to 2 1/4 with a 4 inch collector on my 422.
Are these something you are building yourself? Or do you have someone lined up to build them?
These are what I built for my 405ci W-9.. three step
1 7/8- 2 -2 1/8
Those look awesome. I'm sure I'll have to make my own headers but figured I'd ask about 1967dartgt's set. I really don't want to make a set for my car, lol.
The one thing you want to TRY for is having equal
length primaries... this s a timing thing for the
exhaust, so they will draw on the overlap at the
proper time(equal length)... but also.. the number
one thing is to get them to FIT in the car so you
do what you have to to make them fit... on a true
merge collector they have to be designed to fit the
engine and RPM.. they are NOT a one size fits all
