That is Lon's car. It was the loudest car as I recall. I went with Euro headers to get around bi-annual smog check. You need to get new exhaust manifold gaskets and relocate O2 and EGT sensors. US models do not have O2 sensor on section 1. You need to modify your existing section 1. The best approach is get Euro cat and headers.
