Just installed the GT500 Axlebacks. They came with these rubber things over the small threaded studs on each. These could be installed again once the mufflers are on the car. I would be worried they would melt. And I can think of absolutely no valid purpose. So before I throw these in the Trash somebody tell me what they are for?

 

I've never seen anything like this for axlebacks. Maybe for shipping protection? Just a guess

 

Mine came with these too. I scratched my head for a sec and threw them out.

 

I think they were on my GT500 quads too...discarded them. I thought they were handles used in the factory or something like that.

 

Those are alignment tools for the mufflers. On the muffler as well as the OTA pipe, there is a little pin that these slip over to aid in the install.

 

Ding Ding Ding... We have a winner. I knew they would go over both studs. But for the life of me couldn't figure out their purpose once installed. Thanks!

 

^ interesting. I never used them

 

Interesting!

Mine are the 2010ish GT500 axle backs and they have a little metal tag on the end of a thin cable that appeared to serve no purpose so I just left them there. I wonder if those serve a similar function.

 

They are there for ease of install on the factory line. Don't leave them on, obviously.
