Chappell,
Bernd Ramspeck did the resonator install on my Cummins M11 there in Nacogdoches. I am sure he would have an opinion for your engine. He sure does like the change to my Foretravel.
I have noticed much cooler operation especially pulling hills, better acceleration but no real change in the MPG. When standing behind the the exhaust at idle, that engine really breathes. Much more air coming out than before the resonator.
