New guy w/Q about exhaust

[MurlanMade]

Have a 2012 yukon SLT want to know if I should get straight back exhaust or 45'd. If you have pics please post.

This is the Flowmaster American Thunder cat-back. I no longer have the tips, it dumps right after the axle. Going straight out the back may be a bit hard with the spare tire, the tips would have to be wide spaced
