    Do the tail pipes extend out same as a factory dual exhaust?? they were bent in toward each other about 10 degrees, I guess to follow the trunk drop down angle?? Also can aluminized pipe be polished? Chrome tail pipes, one piece, was a option in 1970..

    Asked by: cliff wright
    You are not able to polish aluminized tubing. The Exhaust will exit in the approximate location but may not exit exactly as the OEM exhaust does.
