high flow means it flows a higher amount of exhaust gasses out so car runs better for full effect its best to run larger dumps as well as high flow cat and at least 3 inch zorst from cat back

So those twin pipe exhaust tips should still be replaced with a 3 inch cannon for full effect? (sorry ive no clue)
