I recently installed a 5 inch single grandrock stack on my 02 and it is a bit too loud in the cab for my liking now and was looking for input on wether the internal stack muffler will make a noticable difference in lessening the noise level.
Has anyone gone with and without the muffler and how much of a difference did it make?
The mufflers are inexpensive but I would like to know before spending more money on something if it won't make a noticable difference.
