Hi
Sorry if this is in the wrong section but I thought I might get more help here.

I'm having problems with my exhaust header/manifold spring cutting through the header on my Traxxas revo. I thought it had just worn throught the first time as the pipe is quite old, so I put the spring in the other hole and it done it again within two tanks. Why is this happening?
Thanks for your help
