See the tiny muffler on the lift? I asked Kyle at M4 Exhaust if it would pass the PIR 101 db sound limit. Kyle said he made that muffler for Moto GP and it would not pass any sound test. This is the muffler from my SV. Tomorrow, I’ll be welding the mount I made onto the sub frame. It’s currently perched on the back edge of the exhaust bracket.
