Im not sure of their age but they arent rusted or anything.
They are the delta flows (didnt even realize that until I pulled the part number) so they dont have the resonance at cruise RPM like the old Flows did. The part number is 942543.
Flowmaster shows then center inlet side outlet on the picture of them but they ARENT they are side in and side out on opposite sides.
They are 2.5" in and out. They sell for $109.99 EACH and Im asking $75 for both.
Total to FL should be about $95 shipped. Email me if your interested further, [email protected]
