im a noob when it comes to working on 91 vert, can anyone help me on what i should do to make the install of my exhaust system easy

 

As with working with anyting old and rusty, soak all the old fasteners in something like PB Blaster before trying to break them loose. Also be prepared to replace any damaged/rotten rubber hangers in the system.

 

I recently bought an Electric impact wrench from harbor freight for 45 bucks. Best purchase I ever made, my exhaust came off in 5 minutes. Before you wrench your bolts, spray penetrating oil in liberal amounts on each bolt. Let it sink in for 5 minutes and start wrenching!
