Ok, guess what I got bored and done today? I gutted my muffler as I said I would in earlier posts. This all started when I started noticing how hot the exhaust and other parts around the exhaust was getting. I have multiple threads on this topic. Ok, so I completely removed the exhaust system, and started taking apart the muffler. I first started with removing the 4, 8mm bolts that holds the end cap on. If you look very carefully inside you see in the following order, a baffle with multiple holes cut in it, then behind that you can see what looks like a catalytic converter. So with this in mind, I cut one end of the muffler off and removed the first baffle. Well, to my surprise our mufflers has a 8 inch long, 2.5 inch around catalytic converter installed in it. Now, you all can draw your own conclusions but this is all facts from the automotive world.
1. Catalytic converters get extremely hot.
2. They do create 1-2lbs of back pressure
Also, what don't make sense to me, is the fact that the entire exhaust system is 1 inch inside diameter and the little tail pipe that bolts to the muffler is .25???? I didn't actually measure it but its considerably smaller.
So with all this said, I am going to do a Magnaflow style muffler, straight through with perforated pipe wrapped in steel wool and fiberglass packing.
