So i have been searching for days to help remove headers on my z4. I have seen some diy, but none for 2003 e85/m54 engines. I am having trouble getting the heatshield right above the exhaust manifold. Bc that is in the way, I cant see and reach the bolts holding the headers in place. the later models have 4 bolts holding the heatsheild in place but mine doesnt have any bolts. any idea how to remove this???
