Hey guys do any of you know of a good quiet 5" muffler to put on my truck? I have a flow-pro 5 inch system on it and I would like to replace the muffler with a one that is a lot more quiet. Im leaning to a donaldson just cuz I can get one where I work. Any info would be awsome. I dont want to kill the thing just tone it down a bit. Thanks!!
