I would like to get an aftermarket exhaust for my 2007 DRW 5.9 Cummins. What would you guys recommend? I don't want anything that is really loud with alot of drone going down the highway at 75 MHP. Had a silverline 4" turbo back dual on my old truck. It was ridiculously loud.

 

The 5" I'm running now is more mellow and deeper than any 4" I've had....

 

The 5" with 51" Donaldson I have is GTG.

 

i second bigwheels94. fbd has the pipe and the donaldson muffler is m090535 for $100 from any truck supply place get the turbo back straight pipe kit from fbd and use the delete piping to extend the exhaust out a little further to keep the drw fender cleaner. total time to install is about three hours and a third of that time is removing the old.

 

I didn't mention FBD because Lary dispises him and there were issues when I last recommended to someone about getting his exhaust system.
