Cobra 4 inch slip on exhuast

I Just installed the cobra 4 inch slip on exhaust on my 2011 stryker. While installing I noticed the bolts that hold the muffler onto the mounting bracket was very close to the rear swing arm. It appears that it will hit the swing arm. Is this how it mounts? Or is there something wrong with my mounting bracket. I took it back off to make sure the bracket was stright and it was. Has anyone else noticed this? Will the swing arm hit the mounting bolts, Or is it just me worring too much?

Thanks for any help
