2023 Automatic Gasoline Downpipe exhaust pipes instead of catalytic converters. They were installed on a Charger 5.7 and fit Charger, Chrysler, and Challenger. They likely fit 6.4 as well. They have sensor openings so the engine light won't turn on. There are minor scratches as shown in the pictures, and the blackness is residue from the bags on the road.
