Same mods as you minus the axle back. K&N CAI instead of rotofab
I daily mine as well.
No issues, even had a few comments about who did the exhaust work saying they did an excellent job.
I kept the stock axle back, to be a little more incognito.
Silly BMW 840 tried to keep up with me but couldn't.
Only thing to check is the cross member brace that goes across the mid pipe. The mid pipe when it settles can rattle against it. (known issue with the Speed Engineering 3" X Pipe on our cars.) My shop just shimmied the cross member to avoid the vibration.
