Q-So there really is only a negligible difference between the stock Arrow with spark arrestor and the FMF with spark arrestor? If so, why make the change?
1- Before I got the FMF I was hoping it would be a bit more quiet than the Arrow, w/out being as restrictive as the Husky dB killer.
2-From a purely subjective noise level the FMF seems to me to be more mellow across the sound range, the Arrow has a bit of rasp/ tinniness to me that hurts my ears. ( I've been a bit sensitive to certain sound frequencies , while being tone deaf to others, since I was hit w/ an IED in Iraq)
3- The FMF was on sale for a great price.
In the end 90% of the people out there would be better off saving their $$$$ and sticking w/ the Arrow. Someone had to bite the bullet and do the test run.
