Abstract
A method 30 for making a relatively low profile catalytic converter assembly 10 which is selectively deployed upon a vehicle 14. The catalytic converter assembly 10 is formed from a generally hollow tube or member 34 which is selectively expanded within a die 31. The expanded member 34 receives a pair of catalytic substrate members 54, 56, thereby forming a low profile catalytic converter assembly 10.
Claims14
A method for making a catalytic converter assembly, said method comprising the steps of:
- providing a member;
- selectively expanding a first and a second portion of said member;
- and
- selectively placing a catalytic substrate member within each of said selectively expanded first and second portions of said member, thereby forming a catalytic converter assembly.

A method for making a catalytic converter assembly, said method comprising:
- providing a first substantially tubular member having a certain diameter;
- providing a die having a cavity of a certain desired low profile shape;
- placing said substantially tubular member within said cavity;
- providing a certain medium;
- filling said substantially tubular member with said medium, effective to cause said substantially tubular member to expand within said cavity and causing said expanded substantially tubular member to be formed into said certain desired low profile shape having a first expanded portion, a second expanded portion which is substantially identical to said first expanded portion, and a middle portion having a second diameter which is substantially equal to said certain diameter;
- draining said medium from said selectively expanded member;
- removing said expanded substantially tubular member from said die;
- selectively removing a first end portion;
- selectively removing a second end portion;
- providing a first and second catalytic substrate members;
- placing said first catalytic substrate member within said first expanded portion;
- placing said second catalytic substrate member within said second expanded portion;
- selectively attaching said removed first end portion to said first expanded portion;
- selectively attaching said removed second end portion to said second expanded portion;
- and
- selectively bending said first and second end portions, thereby forming a catalytic converter assembly.
