Figured out where and how to stick a muffler on it finally.
Well after talking about different ways of doing things and trying a few different mufflers, I finally went with a crossflow stuck right behind the trans. The brackets are not quite what I plan on using but once I get the pipes hooked on and mounted I will figure out the best way to support the weight of the exhaust without just letting it hang off the manifolds. I can’t really leave the brackets I have on it now though they won’t flex along with the engine enough and will eventually break. The trunk fits just fine around the muffler where it is at now it is kind of in that extra space right behind the license plate. the trunk body curves up under the muffler where it is at now and will not hit anything. I have at least 2 inches clearance around the entire muffler, except the trans mount plate is a bit closer but it is steel so it won’t matter.
Once I get the pipes fit on it I hope the drive back home doesnt overheat the body and discolor the paint. I will wrap the entire exhaust with heat wrap once it is home where I can work on it again. I hope that once it is wrapped up that it will contain the heat in the exhaust and not let much of it get back to the engine or transmission.
