Cutouts are great for the street but after only 7 months I destroyed mine! I drive about 70% on road and 30% off but the kit I had just couldn't handle the beating I had the badlanz kit and it was great till the motor fell off the cutout! Haha so I just took off te butterfly valve and motor and let it dump out!
Same experience here. I contacted Badlanz and they told me to bend something or other to stop it from rattling. Suffice it to say I was a little underwhelmed by their "warranty". It doesn't rattle when its open so I pretty much just leave it there unless I go on a long freeway drive where I can't hear the rattle when it's closed anyway.
I'd say my cutout just sits open 95% of the time anymore. I may as well just straight pipe my truck.
