I just recently put on an E-series can on my 650R. 12 disks and the spark arrestor, Problem is the exhaust is comming out the disks (because of the spark arrestor) and has started melting my rear fender! So I take the spark arrestor off, left 12 disks on. Way too loud!!! Spark Arrestor off and 1 disk, still too loud... My question: Has anyone drilled a couple holes in the spark arrestor? I want to run the exhaust out the end instead of out the sides though the disks, but don't want to wake up the sheriff Thoughts?
