If u have the stock exhaust then most likely as its a 1 piece header. If u have an aftermarket header thats individual pipes that hook to the collector(s) then u can get away w loosening the clamps at the head amd swinging them out of the way. Potentially. If u dont loosen them u will destroy the exhaust gaskets almost guaranteed. Then ull b pulling them anyway.
If you need to remove the oil pan and presumably reinstall one, you are best to remove the exhaust. If not, you will be working around it to clean gasket surface, install new pan, install bolts and get everything torqued properly. Do it right the first time or risk doing it again. JMHO.
