I have the complete tti system to include the tips. You are correct the tti tip does not have the hold mechanism welded to them, but instead it is on the tti tailpipes as shown in your picture. The tti tips are shorter and will connect with a clamp, after you cut off the tail pipe turn-downs, and you will leave the tail pipe hold mechanism in place. This allows you to adjust how far the tips stick out past the bumper.
