Default Rattle in sidepipe
It's a baffle broken loose. The stock side pipes have two small and IMHO very restrictive baffles. When mine started to rattle I cut them off, both side pipes GONE> Bought Cobra Paks> you can roll a tennis ball thru these front to back. Great sound and I picked up 20 hp and 23 ft lbs tq. PS< had the entire system chromed to match the 17" full chrome knock off wheels.
