2F Exhaust manifold: Bolt Size & Thread Pitch? (1 Viewer)

[JCKruiser]

Does anyone know what the bolt size and thread pitch for linking the factory 2F exhaust manifold to the initial exhaust line flange? If anyone has the Toyota Part#, please share! Thanks!!

Mine are M8 x 1.25mm, and while I have a H motor, I would think they were standard?

Not too sure, I picked up some M10x1.25mm and they were not the correct fit, I am assuming the M8x1.25s will do the trick. Thanks for the insight!

Are these studs longer than the original OEM studs? Thanks!

YES ,

both with the additional male threads of 21mm /

and the extra hex-lobular hand drive area no threads

this allows for a nice line-up and up-set of the down pipe flange


these are the best DAM Toyota oem M8 exhaust studs ever produces , and the matching correct new modern 2023 flange / anti-come loose nuts are A+ bench mark TOUOTA still in use today ....


thanks for asking this , i need to take a side by photo ,

also

these are perfect for the far end one 2F

you hang manifolds on the ctr ones


then TORX hand drive these after the fact , EAZY PEEZY step by FSM steps .../
