Headers

Or you can use the TTI under chassis headers, they make them for B and RB engines and the headers are different. Mine are 3.5 X2"

You have a set of under chassis headers for a big block a-body that have 2" primaries and 3 1/2" collectors? Did TTI custom make these for you? If not, do you have a part number for them? Just curious because I'd definitely be interested in a set for my barracuda...
