I see ...........
I live in an area flooded with straight-piped diesel exhausts. Dodge, Ford, Chevrolet and a myriad of medium and heavy duty trucks. As usual,
they just sound like they have more oomph. Personally, I could do without all the noise pollution.
I had a diesel Ford that the PO had installed glass-pack mufflers on. Hated the noise, especially on any trip greater than 30 minutes. I've seen/heard vehicles with a "rumbling" exhaust noise that isn't too bad. But, as previously mentioned, a "blatty" exhaust note just sounds immature to me. (Fart can exhausts come to mind.) On a classic car, I just don't see the point.
