Searched, need some opinions on exhaust cutouts
 

So Im running open DP right now and as much as I like it, I know soon I will to get an exhaust again. I love how fast the turbo spools up open dp, So I was thining of doing an E-Cutout. I have hard some good things about qtec cutouts but there doesnt seem to be alot of info on cutouts in general. How many peoples fail and stay open closed?
