I ordered these parts from nissan parts dept.
2x Exhaust metal gaskets (part #14036-7S001)
4x Manifold to collector stud bolts (part #14064-JG30B)
2x Exhaust collector o-ring gaskets (part #20691-30P00)
All for $59.52 shipped.
Here are pics of all the parts and a pic of the new doug thorley collector bolts compared to the factory studs.
Also the doug thorley studs put into the collector.
hope these help!
I bought flange gaskets for collector to B pipe in addition to the O-rings. Are the flange gaskets needed?
I just received the headers and the collector bolts look fine to me. Same as your pic.
von made me some B-pipes with custom bend pipe with MF cats & flanges and I have JBA cat-back. I think I am getting pretty close to set once I get the gasket situation straight.
I have the metal Nissan OEM head to exhaust manifold gaskets.
I have the header collector to B Pipe metal O-rings.
Do you use a metal flange gasket between the collector flange and the B-Pipe flange?
Do you use a metal flange gasket between the aft end of the B-Pipe and the JBA cat-back flange?
