Just wondering what guys on here are running for mufflers it's a 03 4x4 4 door want something that sounds decent but not to lowed make a lot of 300+ mile trips and about 1.5 hrs of freeway driving every weekend smog components are non functional if you get my drift

 

I installed a Walker Dynomax cat-back exhaust kit on mine. It worked and sounded nice. Muffler lasted about 6 years. I had to replace it recently and wanted to keep with the Dynomax kit but I couldn't find one. So I went with a stock replacement. In hopes of having it last longer, I painted it with high-temp exhaust paint. Time will tell if it was worth the effort.
