Just like you, I had to have this replaced on my GTS because it got rusted and started falling apart

part number for the pipe: 16268-15011
part number for the o-ring: 96711-24013

shouldn't be no more than $20 bucks

What's the signifcance of that thermostat bypass tube (16268)?

What are the cons of deleting that tube, and welding the holes on the thermostat housing and water neck/inlet shut?

I don't see any advantage to changing that?

I mean MR2 and FWDs don't have that tube, but they route coolant different anyways.

It interests me because it simplifies things further, and it would make it easier to remove the parts it's attached to - if needed - if it wasn't there.

I know people have done it, but I usually only see it removed on 20v's running 16v water flow and pump. It's obviously there for a reason though and I'm curious what that is, and also what the cons are to removing it.

dont do it. when the thermostat is closed, the water pump is still running, and circulating the water thru the motor, and that pipe. delete it, and theres no circulation...unless the thermostat is open.
anyone studied this before?

imo, the only "safe" way of deleting that, would be to also drill some holes in your thermostat to keep the flow going. but i would just leave it alone, even though it is a pain when taking stuff out. i actually added a bypass in my 20v rwd flow setup after researching about this. i retained the rwd backing plate, welded a barb in the place of the pipe, and made an adapter to bolt the 16v rwd upper waterneck to the 20v head, and just used some heater core lines to connect the two. heres what i did if anyones interested, works great.

Thanks for the reply. Now that you mention it I remember people talking about drilling holes in the thermostat to retain some type of bypass.

I'd be curious to hear from anyone that removed the bypass tube, and drilled holes in their thermostat.

The FWD 16Vs do have a bypass pipe but it goes from the coolant outlet pipe, runs under the intake manifold and into the remote thermostat housing.
