Kakimoto Racing hyper GTbox rear muffler from a 2000 Toyota bB NCP31 2WD with 1NZ-FE. This example is a repair or parts candidate.
The source grades it as junk due to internal baffle failure. It also reports a distorted flange and a corroded silencer retaining screw that will not loosen. Do not treat it as a ready-to-install exhaust component.
