Yes I too found my trk to have a slight drone. My 2007 and 2010 had a resonator and my 2012 does not???? Hmmmm not sure why.

 

As far as I know, every 5.7 Tundra with stock exhaust does it, some after markets are even worse;you'll get used to it after a bit

 

Maybe I am not very observant, but I haven't noticed any drone with the stock exhaust.

 

Stock stocks are too quiet Imo. Never had any drone in my 07 or 11


One way to alleviate the drone is to dump the exhaust about 12" after the muffler. Free and easy

 

Sometimes I wish my truck was loader.. it doesnt sound like its running sometimes

 

I agree.

 

This is the like 10th truck ive ever had and its by far the quietest, in fact too quiet.. I drive a ford f350 v10, a 2011 chevy z71 silverado, and a 2006 chevy 6.0 v8 box truck at work all day and all three of them are waaaayyyy louder then my tundra, all are stock exhaust. SO maybe somethings wrong with yours or my 08 is way quieter, lol! The 2011 chevy i drive is a 5.3v8 z71 silverado and its loud stock so im confused why your test drive was quieter?

 

I drove a 5.3 v8 z71 today and when it was sitting at idle it was almost silent. When running down the road you could barley hear it. The problem was the interior was awful and it rode like a bread truck. This is from a previously only chevy owner. My tahow was a 5.3 also and it was same way quiet unless I was standing on it.

Last night drove my buddies 5.3 silverado its an 07 I think same thing couldn't hear it on the way back from lake pulling boat for 75 miles. I am not making this up. The Tundra is louder sitting at a stop and drive you nuts till you get it up over 65mph on the road.

 

Do a turndown after the muffler, that'll clear the drone on quieter exhaust. With my exhaust I run it's loud enough when I get drone it vibrates the dash a little bit.

 

Found some guys talking about using Resonated Exhaust tips on other vehicles. Anyone tried one on a Tundra?

If you don't have a resonator after the muffler I would say to have one installed, it shouldn't cost much at all and then add a resonated tip. Should cut down on your drone and the exhaust should be a tad quieter.

 

I was just thinking that my exhaust was way too quite.

 

I notice every once in a blue moon my exhaust sounds a bit louder when cruising around 60-65. I love it and wish my truck had a deeper, not louder, tone. Just turn the radio up a notch.

 

The problem is I want to drive with the radio off and not go nutz.

turn up the volume on the radio buddy, fixes everything haha

 

has the noise changed over the short time you have owned it?

pre 2012 the trucks were overly quiet, like a big ass prius going down the road, hence why so many of us do exhaust mods cuz it is toooooo quiet...

if they got rid of the after muffler resonator that may have to do with it.

The reason I asked if the sound level has changed is because one time when I was on vacation I filled up with fuel up north and within 10 miles my truck was loud as hell, I loved it, it was night and day difference... after that tank was ran out it was back to normal tho.

 

i hear ya bud, everyone has there thing, and loud exhaust isn't yours. hope you find something that works, would hate to see you get rid of your tundra

 

Its been this loud since I bought it. didn't notice at fist since it was 100+ outside when I bought it AC going full blast covers a lot of noise. My truck is a tss and has a chrome tip from factory I pulled it off tonight and its heavy and double walled. I am thinking after driving it some this may have helped quiet it down. Storms and wind tonight so hard to say for sure.

Why don't you do what I said? You can thank me later

 

maybe get a Prius?

 

I no longer have the stock exhaust, but even with TRD exhaust and intake, my truck is very quiet when idling. It wakes up only when I mesh the pedal.
. . . and I am not young hot rod type.

Perhaps there is something wrong with your truck. Take it to the dealer and have it checked out.

 

There seems to be a dis-connect between the exhaust note outside the truck and the drone heard inside.Mine has been annoying since new. I stood road side while a friend drove the truck by me several times;the exhaust note from the tail pipe was, as described, quite, however the drone inside at between 40 and 60 MPH is truely annoying. I've become accustomed to it, but at times it is still annoying and I have no desire to cut off a perfectly good tail pipe and dump highly corrosive exhaust gasses under the truck body

 

Exactly what he said. Thanks!

 

Don't quote me on this, but I've heard the solution to your problems is DT long-tube headers, cat delete, and glass packs. Suppose to make the truck as quiet as a Camry. Try it out and report back

 

Sonny, I was running headers and glass packs before you were a twinkle in your old man's eye;don't cure nothin', but surely sets you up for "excessive noise" citations

 

what JC said, turndowns won't cause you any problems at all. You don't have to do a straight turndown you can have them angled as well.

 

Spray-on sound deading application under the cab of the truck, Maybe.

 

My 12 5.7 CM has the drone. I have 5K on it now. One thing I did notice was last week I filled up with 93 octane when I was going to take the camper home to see if it helped. To my surprise, it did not sound like a diesel anymore when at idle, and it did quiet the drone down a good bit, even when not towing.

Should a higher octane gas quiet the lifters in the 5.7 that much, even when there is no load on the truck?

Now that I have run out the 93, and started putting 87 back in it, the drone, and lifters are getting loud again.

 

Octane shoudln't affect the lifters at all. Only engine ping in the cumbustion chamber. I now have over 4k on my truck. I have also noticed the engine seems a little louder from the valve train. I wonder if its this light weight oil? have you had your 5k service yet? Lots of guys talk about going from 0-20 to 0-30 and the engine quieting down.

 

I thought my 2012 was pretty quiet. I added a ba muffler and it drones around 2k rpm pretty loudly. Other rpm lower are very quiet and other Rpm higher have less drone. If the resonator on prior years is after the muffler I don't think my 2012 has one.

No, I am going for my 5K this week. The dealer was trying to talk me into waiting for 10K, but since I tow my camper, I don't want to wait that long. They said ok, but they are going to cover only 2 oil changes regardless of when I bring it in.

Yes, I have seen where a slightly heavier oil with quiet it down. Was it 0-30 or going 5-20?

Either way, there are times at a drive through it almost sounds like a diesel running. Drives me nuts at times, but still not near as bad as the Hemi tick lol.

 

Is your truck a flex fuel? Did you get the toyota care book that says when you should have changes? Here is page in my book stating every 5k at toyotas expense. Don't let them short change you. http://www.tundratalk.net/forums/tu...undra-general-discussion/111170-2012-5-7ff-uses-0-20w-synthetic-5k-changes.html

Funny you said the thing about the diesel sound I have been thinking my engine may be getting louder lately. I just filled up a couple days ago but may try a higher octane on next fill up. I was also asking about oil because I was wondering is this stuff breaking down to quick. I will be doing a OA when I get mine changed in the next month.
