Cut outs

Thinking about putting electric cut outs on my 69 Dart 340 with TTI headers, any pros or cons and best installation set up, (location). Thanks..
Had electric cut-outs on my Hemi Duster...would never go back to them now that they are removed (installed full TTI exhaust). They constantly had issues of not wanting to shut all the way, bolts falling out, etc.. Sounded cool when they worked, but not worth the hassle....
