did a search and couldn't find anything. I need to know what size the stock exhuast pipe is on an 08 silverado 2500hd with the 6.0 so i can order a new muffler. I am going to go with a cherry bomb glasspack or thrush glasspack.

I'm pretty sure its 2.75"

So if i go with a 3" inlet/outlet I should be fine then. thanks for the info. I know people get tired of hearing these same questions over and over but it can take hours to go through everything the search engine brings up and I simply don't have the time to do so.

6.0 has dual 2.5s in and a single 3 comming out

so a dual 2.5 in out would be your best bet

It has a single in/out. A friend of mine took an adjustable wrench the other day and used it to check the outside diameter of the pipe and he said it was 3.25" for both the inlet and outlet.

go with the 3 inch in and out. I just had 2.5 inch bullets put on the SS and the guy that put them on said that they were smaller than the pipe. he said the 6.0 was 2.75 not 2.5 like the 5.3.
