These headers are designed specifically for use in the MKII MR2 chassis with a 2GR swap. the outlet location does not match the stock y-pipe, a custom y-pipe will need to be created.
These come with an embossed steel gaskets for the head(stock style) and remflex gaskets (PN#6006) for the outlets.
There are no O2 sensor bungs in the manifolds, the primary O2 sensors need to be mounted in the y-pipe.
The outlets are 2.25" with a 3.5" bolt pattern.
