Trying to change the Auto Transmission Fluid on my 98 Blazer 2wd 4.3ltr but the driver side Exhuast crossover is right under the pan.

The poor thing (blazer) has 160k miles so I'm thinking it's not the stock exhaust since this isn't even the stock block. If this is how the exhaust is supposed to be

, please tell me the best way to get the pan off. If not, my neighbors side grinder is about to be my new best friend and the local Exh shop can reroute it when I'm done. Any help would be appreciated.
