cage looks good man... I would highly suggest adding some triangulation and gussets in there.... one of the worst parts about an exo is they are a pain in the ass to get door bars into (A pillar to B pillar bar) which is one of the most important parts of the cage. The reality is exo cages are more for looks than structure as they require so many bends to make them fit tight and bends make metal weak... If I were you I would invest in a rule book from an offroad racing organization (SNORE or SCORE) and read up on the cage section for some strength ideas.... its lookin good though!
