Hi all, just came across the site looking for info on my 04 TCD. I got to reading some of the threads and was overwelmed by all the different topics. I had know idea there were so many up grades available for diesels.waytogo I'm more than happy with my dodge as it is, but there is always room for improvement. I was looking for a replacement muffler since mine rusted out, but now am considering a whole new system. Any info on the different systems out there would be great, ease of install. is a big one since I'll be doing all the work in the drive.
