Good muffler for the price

I have a 02 Durango that I cut the muffler off and ran straight pipe. I couldn't stand how loud and obnoxious it was. I purchased this thrush muffler and had it installed. Definitely gave me exactly what I was looking for. A good but mellow tone that won't attract unwanted attention. And for a good price.
