ebay, summit, jegs you check all of those?

 

www.autoanything.com, www.jcwhitney.com... pretty much an exhaust for the 5.9 will fit the 3.9..

 

is the dynomax 17733 super turbo the right one ans what kinda tip is good for a side exit

 

any muffler basically thats a 2.5 in and out a muffler shop can fab up to fit even a 2.25 in/out or 3 in/out they could make work, if your doing it yourself make sure you don't mind at least minor leaks unless your welding it...i like 15 degree rolled tips for side exit personally
