Just was wondering if anyone has experienced interior drone noise inside the cab after deleting everything.
I'm looking at doing the H&S mini Maxx with the delete pipe and egr delete.
I already have a S&B CAI kit on.
I'm wondering if I should find a kit that has a muffler or not.
I have the delete pipe on mine, and cant even hear the exhaust inside the cab. With the radio off, you can kind of hear the turbo in the cab, but not the exhaust. Roll the windows down and that is a different story.
without a muffler you will hear the VGT vanes open and close, and its very loud. I liked it for a week or 2 . let me know if I can help ya out with a muffled exhaust.
This all comes down to personal preference. A straight pipe on the 6.7 is a little quieter than a straight piped 7.3. If you put a delete pipe on without a muffler, you can always cut a muffler in later. Some guys use a 51" muffler and are happy. I mistakenly ordered a 40" and I decided to give it a try. I'm pleased with the amount of noise and it is approximately 50% of the straight pipe noise level. I would recommend a stainless down-pipe back 4" with a muffler and no chrome tip to keep clean.
My 5" is definitely louder in the cab compared to stock (obviously). The drone is really not annoying at all and is only really noticeable while accelerating under a load. It's not not nearly as obnoxious as a straight piped cummins, or even Flow Masters on a gas.
anyone have pics of their setup underneath? with the muffler. im looking to keep the stock tail section on as I like the twin pipe design that Ford used.
Thank again for your replies
I use Gearhead too. Haha. There was a thread where you and Carli'6.7 basically walked me through on how to get them. I already knew you had Gearhead tunes, but I was able to know from the video because mine sounds and shifts the exact same way..
How are you guys liking the gearhead trans tunes? Ive just switched to the h&s canned delete tunes with trans and Im seeing some quirks I dont particularily like. Truck under full throttle from 1-2 shift the other day bounced off the limiter and jumped to neutral. I think the TC had something to do with that though. Havent had any issues since then but I havent pushed any 0-60 runs either.
Gearhead's transmission tune is great in my opinion. I've been using it for 3-4 months now and haven't had any issues. I'm kinda done with the "speed test" phase and I drive normal now, but it'll be firm when you need it to and smooth when you don't.
Just curious but without having to do a delete, if I just take off the muffler will this thing sound like a diesel should again? My 2015 will be here eventually but as hard as it will be for me, I'm gonna keep it stock minus the lift and wheels/tires. Having warranty and piece of mind on a 65k truck is nice. I would like it to sound good though.
Unfortunately, there is no muffler to take off. All of the emissions/sound control equipment is one self contained unit and there's no way to separate any of it. The only way to get any noise out of these is to delete.
There's a small resonator on the tailpipe section of the stock exhaust. I think it says in the owner's manual that any modification to the intake, exhaust, or programming can result in a voided warranty. I modified the DPF-back exhaust with MBRP dual tips before I deleted and figured they could technically void my warranty right there.
