I went for a fun trip last week to Glamis with my 2018 RZR Turbo, which has an Agency Choice exhaust. While riding, I noticed an exhaust leak... I found a nut and stud on the manifold had come loose. I tightened them, but the leak's still there. I'm not sure what else to check, maybe a gasket or a crack somewhere? If anyone has dealt with this or has ideas on what to look for next, I'd really appreciate the help

Exhaust leak trouble after Glamis ride

It looks like the manifold might be loose because a gasket failed after a nut got loose. You can try putting some Sea Foam in through the intake. You'll see a lot of smoke from the exhuast, which will help you find the leak
@James_B yep, a persistent leak after tightening a nut is usually a blown gasket.
The pressure and heat from the turbo are extreme, and when a stud or nut loosens, it allows the exhaust gases to blow out and destroy the gasket.
Even a brand new gasket can fail if there's any gap. You'll need to remove the exhaust and replace the manifold gasket and possibly the donut gasket where the downpipe meets the turbo
