I just purchased a pair of sporty mufflers off ebay to do the muffler conversion. I have a questions for anyone that has experience with this. When I look down the barrels of each muffler, they appear to be different. On one of them, I cant see any light and it appears to be baffled. On the other I can see light and it appears to have only a small peice of baffling that almost looks like a loose obstruction. Which muffler do I use.

Thanks in advance
