So getting my car ready after TVS swap to bring to Bill at Pro Edge tuning next weekend he highly suggested removing my high flow cats as they will not handle the heat/boost and are prone to failure, so i removed my cats tonight and to my surprise passenger side starting to fail. This was just from a upper pulley and cold air at 13lbs of boost 550hp. Anyone with Dynatech cats please be aware and check them thank god i caught it now before the higher boost ill be running with my tvs.
