I put this off till now, I noticed this when I installed the exhaust but it's nothing big and now that I have the free time I'm going to look for a solution.



The blue illustrates air, now this air isn't pouring out but it's definitely coming out and I'm sure in 5th half throttle it's making a bit of flow.

The red illustrates the wear mark on the aluminum piece that fits exhaust on the header, I think that is caused from this.



The bolt they gave me to use in conjunction with the spacer is a bit longer than that red line. The piece it gets bolted into has two sets of threads and the bolt only goes through one set allowing minor movement.

Also when this bolt gets tightened it usually stops most of the pipe movement but never seems to keep it from moving in 2 days.



Hope you guys can help me.
