does everyone think its safe to run 3" mild steel true dual through a x pipe wihtout putting and flex couplings anywhere. was thinkin of going with solid motor mounts or do you think its okay to run a solid exhaust

 

You could try it and find out, but I think having flex couplings up by the engine wouldn't be a bad idea at all.

 

You don't need flex couplings anywhere. Just use OEM style rubber hangers so it has some room to move around. Don't mount it with rigid hangers.
