Muffler Cut-away View
Does anyone have the stock LT1 muffler cutaway view? I'm curious to see what the inside of the muffler looks like... I know someone attempted to get this info unsuccessfully before but I figured it was worth another try.
It wouldnt hurt if you have other C4 muffler cutaways to post up too (stock and after-market).

Here's a stock 1989 Muffle cut in half.
Not that I'm an expert is gas movement or muffler design but.......
Basically the exhaust enters through the center tube into a small expansion chamber. From there some of the exhaust is forced into the smaller center tube on the back half of the muffler. I'm guessing this design creates back pressure that then forces the incoming exhaust into the baffle on the right side of the front of the muffler. From there the exhaust is turned around in the front half of the muffler and sent out the left side to the exhaust tip. I might have my right and left side confused, but you get the idea.
the exhaust comes in the middle to an expansion chamber, gets turned around the front half of the muffler and then goes out the exhaust tip. The back of the muffler is a pretty much an empty chamber.
