OEM manifolds, y-pipe and cats. Taken off my recently sold 2002 GMC so I could install long tubes. OEM parts never leaked, no holes, great shape. Cats still flow, no codes at time of removal. Cut in center of y-pipe (where crosses under trans) to facilitate easy install/removal. Can provide with band clamps that I had left over from long tube header install. Asking $125 plus shipping.
