OK after the hole between the bottom bolts kept blowing exhaust,I called summit racing.And guess what wrong header for my 4 runner.So the tech guy at summit called DT.And they said the only difference in that header and the one I have is the hole in the flange between the bottom bolts.So they told me to remove the header and Tap that hole in the head and put a threaded plug in.Also they are sending me a new gasket set for it free.
Sound like it will work?The header fits perfect except for the leak.
