After an exhaustive
image search on Google and Bing, I have determined that the image posted by sunroofcuda is NOT a Flowmaster muffler. It is a Flowsound muffler. I was unanble to find a cut away image of a center in / center out Flowmaster race muffler.
However, I did find this image of a single chamber Flowmaster. So I assume the center in / center out would be similar.
Regardless, I'll try some Ultra Flows next season. My exhaust is set up so I can easily change from my little single chambers and dumps, to the three chambers and dumps or tailpipes. I'll just add a third option to the mix.
And I'd be happy if it would pick some ET.
