Electric exhaust cut outs

I bought a set and was going to install them before the x pipe, which I wanted also but with the x pipe positioned up where it belongs, there was really no room unless I cut them in. They do make an x pipe that has cutout flanges also but I didn't purchase that kind.
I decided not to install them and ran 2.5 out the back with tips and glad I didn't. The x pipe was a big plus compared to straight duals tho. I am extremely happy with that and won't install exhaust without it ever again.
If I want open headers, I can just unbolt the flanges. Timing can need changed when cutouts are open also so to me, they are a waste, but to each, his own.
I highly recommend an x pipe tho.
