I just finished replacing my Ultimate Racing High flow cats for another set of UTRs. I have to give a huge thanks to Z1 Auto and Ultimate racing for getting these to me so fast. I called to order replacements this past Monday (9/13) and I had them at my door Thursday (9/16). They are built on demand and really hustled to get them to me.

My original UTRs were an older model with a bracket welded to the body where the OEM cat bracket rides, and this ripped out a few weeks ago. I had patched it temporarily, and just got around to getting it done. The new cats did not have this bracket.
