Here is a set of custom stainless header we did for a car running the Super Modified class. The engine is a GM 604 crate engine with D-port heads and we chose to run a 1.75” primary tube with a 3” outlet going to a true merge collector. To make these headers legal to use we had to be sure to include a class approved Dynatech muffler. Although the polishing was not needing it definitely looks amazing and stands out from the other cars.
