2 ?'s. Exhaust sz.,&temp. sensor

I have rams horns on my 86 ,5.7l chevy sb. I had the local muff. sh. make some stub outs that fit them and they r 2"" OD. I want to use Flowmaster U-FIT dual exhaust. That is 2.5" OD. So I need to have a adapter 2"-2.25" then another 2.25"-2.5".Thats gonna look kinda ugly. Is there another way.

I have a mechanical sensor for my temp ga. I have no ports on my intake for temp. I have an electrical sender on the pass. side of the block that is so rusted in I don't want to break it off.
What are my options?:confused:

Anybody? Thanx

Use Hooker slip-on reducers, 2" to 2 1/2". Pictured here at the top of the photo (no flange)....

Some motors took the temp off the head, some off the manifold at the very front. Here is a photo I found showing the outlets at the front of the manifold and also a threaded bung on the thermostat housing where you could mount a sender, but I would only do that as a last resort. By the way, I didn't draw the yellow arrows, they were already on the pic.
