Not half as bad as those ridiculous Cummins guys. Those only sound good with a sport muffler on them. straight pipe sounds like a tractor plowing a field.
I have to agree with getting the exhaust above inhalation level. Being that mine is a plow truck and spends a lot of time going back and forth short distances, I also used to smell it a lot when I had underbody exhaust. I don't have any experience with dual stacks, however. My only bit of advice is don't try straight piping it. Doesn't even sound close to good.
Curious how you routed that and if it's hard bolted to the frame for support. I got to thinking about doing this at some point because the stock exhaust routing is actually kind of problematic on the cab and chassis trucks with the rear mounted steel fuel tank. My aftermarket 4" would bang into the front passenger side corner of the fuel tank until I rigged up a fix for it, but it would be a lot cleaner to totally delete that rear section of exhaust. Hard mounted to the frame like on a semi tractor you'd need a section of flex pipe somewhere between that and the motor. Looks proper on a dump truck though.

Depends on the generation. The 12V and early 24V up to 2002 sound ok straight. It's the commonrail ones with the asymmetrical exhaust manifold that sound like a pissed-off bumble bee.

I haven't had a muffler on the truck since shortly after I purchased it just over 2 years and 100k miles ago. I've always thought it sounded good, a little loud outside but not overly loud inside IMHO. Is the stacks going to make it that much louder, i couldn't imagine it would. Also I am planning on running them about a foot over the cab to try to get that smell as high as possible
Mine had an ugly 4" straight when I bought it...it wasn't intolerable but I eventually chucked it for for Flo-pro bolt on setup with a muffler and it did take the edge off the exhaust blatt which I called a win. I'm getting old I guess. I don't like noisy exhausts or tire rumble and have no idea why anybody would bother making their car stereo louder. I must have accidently grown up at some point (yikes)

Funny you say that, interference with the fuel tank is part of the reason I did mine (the first iteration was 4", this shows the upgrade to 5" to allow for the internal muffler).
As you can see, I have a piece of 4" SS flex in there.

Straight pipe sounds good at idle, but as Brandon said, the blatt is just awful. I don't have a problem with a somewhat loud exhaust if it's toned correctly. But you'll never get a nice low growl that the big rigs make with these small engines.
