This is a simple question is it hard to put a header on my car...its a 1997 eclipse rs? its from Greddy

well its not hard to put on. I put some headers on my car the other week. I think the hard part is jus gettin the heat shield off, that was a pain in the ass. But other than that it was easy. ANother problem i had was the sensor. ALso make sure you tighten it good cause now i have a leak somewhere and i gotta fix it. ALso make sure you polish them with chrome cleaner, i prefer momma cleaner. If not they will turn gold and blue.

nah its, not hard, changing out one on a gst or gsx is a lot trickier though. and make sure it has the bung for the o2 sensor installed already (unless you can weld), and the right manifold gasket ( they get mixed up sometimes.
good luck

Use anti-seize when installing the header
