Is there any drone with a straight pipe exhaust?
 

I've heard a cummins from the outside that I THINK had a 4" straightpipe and it souded great, but wasnt super loud far away (got half way down the freeway ramp and I couldnt hear it anymore.

I am interested in going this route, but wondered if they could be driven "quitely" so as to not piss my neighbors off, and dont really want to have a miserable time cruizing at 70 on the fwy.

Any input?

I'm not sure if you could drive it quietly enough to not piss off your neighbors, I guess it depends on how picky they are. They aren't too bad on the highway, there is definitely some exhaust noise but not something you can't cover with the radio.

In my experience at about 1900-2200rpm there will be a drone that will drive you crazy. Your neighbors wont be happy, but that can be dealt with. :c:

there is a drone with any non muffled vehicle some worse than others hope you have a loud radio

Seems to depend on the truck. Also seems to be worse with a long box truck. I know its not a third gen but I had my 98 shortbox straightpiped for awhile. No drone at all. My buddys 97 longbox had so much drone his kids couldnt go on a long trip. He ended ripping out the interior and installing dynamat.

Interesting... You would think it would be worse with a short box. I'm running just a cat and it's fine. I would like to pull the cat too but I'm worried about it getting too "droany"

My 05 with a shortbox was straightpiped and had a loud drone. dads 05 with longbox has a little but not as bad as my shortbox. onl;y difference in the two was my pipe did not stick out at all and dads sticks out about 3"ish. His long box definatly outside the cab was louder though.

I have an 07 straight piped and it pretty loud and yes it does have a drone but sounds darn good.

I think that has more to do with the droan inside the cab more than the length of the box. It will always be loud outside the truck but your neighbors will get used to it!

any exhausts with a resonator in them with no real muffler/ I want to hear the truck, but dont want to go deaf or get a migraine drivign across town. I wish I knew a single other local person with a cummins

Is there an exhaust that is straight pipe catback? I'm not an environmentalist o ranything but I see no reason to NOT leave the cat in place... that sounds like the route for me. Or do you just have an exhaust guy do it.

Our turbo back straight pipe kits for trucks with cats are designed to either delete or keep the cat.

My '03 str8 piped has a pretty good drone right at 70-73 mph, slower or faster and it fades away...

Ive had a 06 CC short bed and a 04 CC long bed, both straight piped. I didnt notice a drone at all except for going up serious grades, or towing. On that note I think Im getting old b/c Im about to throw a muffler on.

What gears, cab size and trim level is it? This will also make a difference.

On my 04 Dodge Cummins I have a straight 4inch piping with no reducers all the way back then a 5inch tip. When cruising down the highway you wont no you have a straight pipe unless your outside the truck. My neighbors dont get bothered that much and I live on a hill so when I reverse out of my driveway I have a pretty big hill to climb, then its pretty loud. Its your choice what you do to your truck dont base it on your neighbors. If you want a straight pipe, shoot put it on there. You will not regret it. straight pipe on a cummins is the best sound too. Good luck:tu:

^^ Ditto. I have a mega cab with no cat or muffler but the resonator is still on it, and it sounds good and I really don't have any drone. If I do, it's only for a breif period up through the RPM's and then it will go away (like 100rpm range or so). With the windows up and the AC on and the radio on it's barely noticable unless I stomp on it.

I've somewhat re-thought my changes... I'd like to keep cat in place... for emissions testing and why not... would a catback or muffler delete even be worth while? (sound wise?)

My 2nd gen has no drone:nope:, its straight piped:tu:4"

I would say if your not going to gut it the whole way, then I wouldn't spend the money on a system and I would just delete the muffler. It will sound different no doubt but I don't know how much different. I don't have my muffler or cat but I still have my resonator and it's pretty loud. I do plan on upgrading to a 5" system some day but for now and the money it cost, I would just gut the stock pipe.

Yes you can drive it if you soft shoe it. I have a 03 4 door long bed and it does not make much till I get on it. So go ahead and do it . Keep your muffler. You can get a 03 04 kit from [url=http://www.genoesgarage.com] for 69.95 that you can put on it. If you don't like it you can put the muffler back on. Don't let any one cut off the muffler!! DO IT WRIGHT. === good luck === :tu:
