Interesting everyone is saying FF tune quieted it down, I've been running my E85R tune and yesterday wanted to run some 93 through it since it had been a while; switched to flex and its a lot quieter. I think its the change in gas that's making it quieter for a day of two.
I have SW catless, x pipe and muffler delete, not sure I even know what quiet is anymore. I will be putting my stock axle back on soon.
