I know there is a place in Australia i think that makes headers for this engine...... I found it online before but i made the mistake of not boookmarking it. Now I cant find it for the life of me anyone know the website? or any other company that makes headers for this engine.....

 

Plenty of places in the states that make them.

 

......no they dont.... they sell plenty of parts for the 4g63 but not the 4g64
