All I can say is wow. This muffler has met all the criteria I was looking for. Free flow, quiet operation and no drone.
I had installed and had the kitty taken out for testing purposes
Truck has a nice rumble at idle that defiantely sounds meaner but when I started driving it I couldn't even tell I had it installed.
For anyone looking for more endorsement on these mufflers i'll definately give it mine. I did not in any way want a loud diesel and I don't have one.

 

Do you have a pic to post.
Is it Straight through or baffled?

 

Sorry for the slow reply. It is the straight through model. After hearing how it sounds I wouldn't bother going with the baffled one. It is very quiet.
I'll take some pics this afternoon for you and post them of the install.
