Hey everyone im new to the forum. I just recently got a 05 ram 1500 5.7 hemi and was wondering what the inlet to the muffler and out let sizes were. I want to put something on there to make i a little bit louder.

Thank you!

 

its between 2 and 3 inches, depends what you've got down there. Only way to be sure is to climb under and measure. Stock muffler is 3" inlet 3" outlet I believe.
