Straight pipe - does it drone?

Curious if the straight pipe setup drone and or if they are wicked loud. I don't want to **** off the neighbors while warming up either.. I love good sounding exhaust and will straight pipe it if ya'll give it a good review.

Mine's been straight piped since day 1. I don't think you'll **** off your neighbors starting it up and letting idle, it's mostly engine noise at that point (or at least my truck is) with minimal turbo whistle. As soon as I get to rolling down the street, she's a bit louder. I usually put it in 2nd and try to keep the rev's down until I clear the end of the street in the morning.

Is your cat still in place? that's the most restrictive part of the exhaust, (well, that and the downpipe) our mufflers are already a straight-through design. You could always ditch the cat and the DP to start, and see how the sound level is. Then try ditching the muffler

I don't think they're very loud. A little bit when you really get on it. My straight pipe does drone a little though

Mines loud if you put it on fast idle warming up. If you're in a tight neighborhood, they will hear it like that, or at least I know would hear mine. But, I wouldn't have it any other way either..

I bought the truck from a bud and he had a banks dp installed. I climbed under the truck and see the little kitty and have a feeling it's a bit clogged anyhow.. Should I punch it out or buy a 36 dollar piece of pipe to replace it?

I read in one of the manuals that the muffler is high performance or something to that effect. Straight through is perfect..

Straight piped turbo diesels do sound awesome, except maybe the 6 cylinder types..

I'd say that's up to your state emissions requirements. some do a visual inspection to 'see' if there's a cat and some don't. Doesn't really matter if you gut or put a blank in performance wise... whatever works for you

No emission tests where I'm at.. I guess knocking out the kitty would be the cheapest option..

My stock exhaust cackled bad but not much drone. My 4" to 5" tail has a dmax tone above 2000 or so.

I did have mine straight piped, but after the 14 hour drive to Yellowstone a couple years back, the better half said put the muffler back in......

I was always told that the muffler provides backpressure that the 7.3 needs. My exhaust is minus the cat .... when I run it without the muffler it sounds awesome, but I swear, with the muffler ..... I seem to have more power with less turbo lag. Anyone ?

That's the rule of thumb I remember for gassers.. gassers lose their low end without back pressure, from what I was told. I was also told that the turbo is the only back pressure needed so IDK...

I've always been in the minority regarding exhaust sound. I can't stand the flutter from the turbo, and straight piping the truck made it worse. I've torn the exhaust off the truck and replaced it with several other options, and this is the only one I consistently like: the cat was already gone when I bought the truck, so I've replaced the downpipe, put the stock muffler back on, and have expanded the exhaust to 5" immediately after the muffler. My exhaust now exits in the stock location, and at idle it sounds stock. Once you get into the throttle, the exhaust note is quite low, thanks to the 5" pipe, and the stock muffler tones the flutter down.

Your mileage may vary.

By the way, your poll only gives two options: straight piped or stock. I'm willing to bet there are trucks with something other than those two options.
