As an update, it looks like I am going to have to either go back to a single or save up and get some aftermarket cans as oppossed to the zx-14 cans. The left side can is hitting the driveshaft when the suspension is compressed. I've tried adjusting it but there's only so much I can do as the mounting points are fixed.
Aftermarket cans will be much smaller in diameter than the zx-14 cans and should eliminate the problem, but boy are they expensive. Stay tuned.
