Anyone know what brand this is? I know it's not factory as it's missing the 02 sensor bung.



I'm trying to figure out all the gaskets I'll need, after re-installing the header.



I seem to be missing 17300, VALVE; and 1719A, Gasket.

I just had the two gaskets after the VALVE: Gasket 17173, and 17177.

Do I need the first two? (17300, 1719A) Any ideas why it would be missing?

Thanks,

ian

According to this thread... http://www.club4ag.com/forums/viewtopic ... 205#p68162



... that is a TRD header (like the one on the left side of the pic).

The 17300 valve is the TVIS plate. The 17179A 8-hole gasket goes in front
of the plate and the 17177 4-hole gasket goes behind the plate. I guess if you
are using the TVIS plate you will need both gaskets. 17173 is the exhaust
manifold gasket, and you definitely will need that

Thanks Johndee! Perfect answer as always!

easy way to tell if TRD or OBX copy look at the EGR hole

TRD= Is straight up, egr lines up, perfect fitment

OBX= is at an Angle and won't line up, must bend egr pipe to fit

thats what i look for first, then the Collector TRD is a nice even collector, deep V
obx not so clean Short V collector
