Exhaust Leak or Something?

[Bazooka SHO]

Several weeks ago I started smelling gas fumes. It must be coming from the engine compartment because I could smell the fumes pretty strong the other day when I had the AC on. Also I notice them when I first start the car. I have noticed what appears to be an exhaust leak at the manifold of somewhere in the engine compartment. I also get CEL code 332 and 176 every now and then. Thanks

332 is dpfe didnt change. search for this code on the forum and 176 is lft o2 sensor not working. but fix the 332 code first before any thing else then erase the codes.
