My deleted 6.7 with 5" turbo back with Flo Pro Twister has a very nice rumble at idle and take off. Also has a nice bit of turbo whistle when taking off. Its just right.
I’ve put hundreds of thousands of miles on the Cat 3406B mechanical engines. Most were in COE Kenworth K1 class 8 trucks. IMO the best class 8 truck engine ever built!3406 425 Hp Cat engine.

I love the sound of the buzzin dozenThe Detroit Diesel 2 strokes. That's about it.
My 300D automatic transmission had a whine at 50 that sounded like it was going 100.I always liked the sound my '82 300D Turbo Diesel made at speed, like 75-80 MPH, a nice throaty roar. The older Cummins always sounded good, especially started cold.
