Dennis Kirban reproduced the early GTO exhaust splitters in the mid 80's. Quite a bit of work went into the tooling. PY & Ames sold his repro's for decades. Believe that tooling is still being used, as have picked up several pair of the splitters over the years with no discernable change. Have never ran across such a intricately design exhaust splitter in a larger diameter inlet. Necking down to the repro splitters shouldn't cost you any measurable torque/hp, do understand the installation won't be as clean.
