Hello, I had a quick question maybe you guys can help me clear up, I just purchased a titanium factory 4.1 muffler for my bike. I was expecting to get something like this. Factory 4.1 but instead received this. Factory 4.1 Whats the difference between the two? Do they make the style that is in the first link for an 03 yz450f? I cannot seem to find a picture of one on a bike that is the same style. Thanks.
