If you are talking about repla ing an old, crud-clogged one with a brand new (likely higher flowing) catalytic converter, while it would not actually make the engine more powerful, it will cause less of the created power to go to waste by removing the restriction it used to have to fight against to extract exhaust.
But if you have a modified car with significantly more engine power than stock (20% increase or better), you will almost certainly see improved engine power switching to high flow catalytic converters (especially top-end performance as measured on a dyno). If you’ve added a supercharger or turbocharger to your vehicle – or substantially increased the boost of an …
