I got my Duttweillers one day, bam, they pop up and you have about 1 day or less to repond before someone else buys them. They are hot commodity. I completely lucked out. I havent seen a set on here for sale for quite some time now. If you have cracked headers I have a complete set that you could port out to make them flow a little better. They have been welded up nice. I just took them off because I got the duttweilers.
