What is the web site for info on the Rok Tech muffler ? Is anyone running one of these ? I am debating between a Rok Tech or a 51 inch Donaldson. I do 90% towing about 5,000 pounds. I'm worried about trying to add muffler hangers on the Donaldson as I don't have a welder. Any reccommendations would be helpful. Thanks.

 

I had a 51" Donaldson on my 04.5 LWB 3500, and it had a significant drone around 70-80 mph. Mine was a 6 speed, and I didn't notice any performance difference, just the louder exhaust.

Figuring out where to weld the hangers was a pain.

 

I replaced my aeroturbine with the "Silent Might" - I am much happier. Be aware there are no Hangers on the Roktech muffler either. I had installed the areoturbine - I paid a muffler shop $50 to install the Roktech, money well spent...
