    isuzu exhaust butterfly ?

    As we know the standard exhaust on a 110 isuzu county is around 2"- 2.25" (i am asuming correct me if I am wrong) I used to hav a exhaust brake on the system but since the turbo has gone on I hav put a dead straight through 3" mandrel exhaust on and am wanting to get a exhaust brake back on it again problem being I cannot find any butterfly valves with 3" ID I hav a valve with a 2.5"ID but don't know how much that will restrict flow in the 3" system ?

    Chief,

    I used a genuine isuzu exhaust brake to suit the 4BD1T from a NPR truck,it measures very close to the ID of 3" exhaust tube.Part number is 92955488.
