I’ve been looking for quite some time now, is there anyone that makes Active/Variable Exhaust kits for 2013-14 mustangs? I’ve seen the cutouts that are just Ys , and I could use those, but I was just seeing if there were any kits before I pieced together my own exhaust. I’m trying to make an exhaust that I can have quiet for late night neighborhood use, but can be swapped to a much louder sound

 

check out the Boss exhaust with the cut-outs

 

The Boss exhaust and cutouts are very nice. The OEM Boss ones might be tough to find, but I believe Kooks use to make a set similar to the Boss Quad exhaust. Might look there as well.
