I have the exact same slip-ons with no problems, Im assuming that you inspected the Rush pipes and found nothing foreign in them (you should be able to see clear through the muffler)
D/C

 

the mufflers were clear and the exhaust was flowing great- great sound, nice and loud till the squeal and overheated head pipe. i'm done messing with it- taking it in next weekend for the super tuner , air cleaner and have it dyno tested.

on another topic i found and exhaust bolt from the crossover touching my rear brake shaft causing it to bind up and not fully engage the brake. i checked out an 09 and the bolt was much shorter and not touching the shaft. So if ya have the 10 check that bolt and have it removed!!
