I have a Primera exhaust manifold. I was wondering what the stock manifold on our Sr20de look like without the heat sheild on?
Does anyone have PICS of this? I already know about Egr and O2 fittings. Also I know i have to cut down my down pipe.
Also how much horse power will I get if I install the Primera exhaust mainfold? Will i get more hp if I grind out the lips inside the piping of the exhaust manifold?
How hp does Stillen and Hot shot Headers produce?
