    was the old converter flared, and the pipes shoved inside, or was the pipe flared and the converter ends shoved inside the pipe??? In other words, where is the pieces you are removing, inside or outside the pipe?

    I usually cut the pipe as close to the end of the good pipe as I can and then split the scrap piece with an exhaust pipe chisel. Good Luck! /forums/images/graemlins/thumb.gif

    I assume you're trying to save money instead of going to a shop? you can grind (cut a groove, peel it off like a C shape) the piece on the outside, and get it off. The inside piece will not be worth the effort, IMO, cut length off and have a shop sell you an extension piece...
