Part number 7195 from Flo Pro - used it for 300 miles, it does the job for sure, however I have a 30" FTE resonator as well and both the muffler with the resonator was stock like sounding so I took the muffler off -

Local pickup preferred - however I will ship, buyer pays actually shipping cost as its got some heft to it -

Pics can be sent to potential buyer as needed just shoot me a PM and if anyone knows any other diesel guys wanting the same muffler for a 4" system let me know - thanks!
