elec. cut outs

I have a set and like them. It's fun messing with people when you pull up to a stop light. I also ran dyno test with open and closed that made it easier. It ran 10HP more through the mufflers. I got "BadlanzHPE Electric Exhaust Cutout"

did you try and up jet with them uncorked? you'll just mess up your AFR if you dont tune it with them open...
