Baffle for Arrow exhaust?
I have a 2009 Daytona track bike with Arrow full titanium exhaust, and under-seat muffler with a single oval outlet. One track I go to has a 104dB sound pressure limit (it’s a county ordinance, not the track owner’s own rule). I was given a warning that my bike is over the limit. I was surprised, as just about every bike there sounded louder than mine. They are measuring sound levels at a location on a straight where I am hard on the gas in 4th gear, at 12 or 13 k. I need to quieten it down a bit.
Does anyone have any suggestions for a baffle that is designed to fit my muffler, or other sound deadening device? The problem is how to hold it in there. I tried a Goldilocks pot scourer, safety wired in (difficult to do, and looked awful) but after two sessions it was working its way out. I reverted to short shifting into 5th, and rolling off the throttle at the sound detection point, but I’d rather not have to do that.
