Power comes in earlier and turbo spool-up is significantly improved. The long gradual transitions within the mandrel bent pipe section allows exhaust gasses to maintain velocity without a buildup of back pressure inside of the system. The CAT is new and specific. It has a newly formulated substrate with a specific wash for new vehicle emissions requirements. It is not an off the shelf cat.
