Exhaust header type?

Postby CloudStrife » Sat Jul 01, 2017 11:47 pm

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.

Image

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 :)

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
