Well my local mechanic looked at it. I am going to take it to a dedicated muffler/exhaust shop tomorrow. I did find this: https://www.gmpartsonline.net/v-2007-chevrolet-silverado-2500-hd-classic--wt--6-0l-v8-gas/exhaust-system--exhaust-components that references a duel intake muffler https://www.gmpartsonline.net/oem-parts/gm-muffler-and-pipe-25929098?c=Zz1leGhhdXN0LXN5c3RlbSZzPWV4aGF1c3QtY29tcG9uZW50cyZsPTcmbj1Bc3NlbWJsaWVzIFBhZ2UmYT1jaGV2cm9sZXQmbz1zaWx2ZXJhZG8tMjUwMC1oZC1jbGFzc2ljJnk9MjAwNyZ0PXd0JmU9Ni0wbC12OC1nYXM%3D Guess ill just hang out and see what the exhaust show has to say. thanks for the reply

I purchased a 2009 2500 HD 6.0L WT (single cab, 8ft bed) this past spring. The muffler is on its last leg. I took it to my local mechanic to have it replaced. We spoke on the phone after he looked at it and gave me a price. Some time later he called me back and said he was unable to find a replacement muffler. All his tools he had at his disposal showed the stock muffler only had 1 intake and 1 outlet. My truck has 2 intakes into the muffler and 1 outlet. I checked https://www.gmpartsonline.net/v-2008-chevrolet-silverado-2500-hd--ltz--6-0l-v8-gas/exhaust-system--exhaust-components and it does show 1 inlet and 1 outlet. Do I have a nonstock setup? I have searched this forum and others appear to have mufflers /w 2 inlets and 1 outlet so perhaps my mechanic just doesn't want to deal with it. Just looking to confirm what I have and what I parts I need for my local muffler shop to get this taken care of. Thanks! Sorry if this is covered in another post.
