Electric Exhaust Cutouts? [and other efficiency mods]

Hey! Didn't immediately find anyone talking about these things in searching.

I'm ordering an exhaust header for my truck this week (PSYCHED!!!!) and potentially a high flow manifold and muffler. I don't want it to sound like crap but a throaty sound and max efficiency are the goal.

Now, somehow on eBay I came across these electric exhaust cutouts.

Oh, I am too noobish to post images or links yet. Go on eBay and search for "electric exhuast cutout" or try some of these keywords "Electric Exhaust Cut Out Cutout Test Y-Pipe Valve Kit Switch".

It would be nifty to install in the back just prior to the muffler, for the sole purpose of having another switch in my interior... Switch of a button, goes instantly dragster loud.

My question is, in a relatively efficient exhaust system (high flow already) will I see a boost in MPG on the highway, or would the loss of backpressure pretty much work against me? Anyone tried these?
