Throttle body size clarification

[RedSRT4Me]

Thanks for the clarification. So which manifolds are we talking about exactly 6.1 or 6.4? And are these from a car or jeep?

Something like this could pass California emissions me thinks



That price is steep but if you can find them cheaper obviously it could be an option.

I wonder how much modifications are needed to fit these? Looks like a solid option to those who are in these areas and limited to whats legal. Appreciate you putting this out there. I went with shorties myself but would of considered these had i known.
