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?
