2017 3500HD 6.0 Mild muffler option advice

EZTundra77 · January 31, 2019

I'm looking for a muffler only swap to my '17 6.0. I dont like it loud. The stock exhaust is almost throaty enough. I'm thinking a Magnaflow XL chambered muff. but I havent been able to hear one on a 6.0/L96. I dont want rasp or loud. Just a little deeper and more audible than stock.

I prefer the Flowmaster, check out their Super 50 muffler. https://www.flowmastermufflers.com/flowmaster/street-mufflers/

My experience with the big magnaflow 3.5" muffler. Still have the mid pipe I made laying around if anyone is interested.

Flowmaster BB50 series. Deep tone, nice rumble. You will gain HP.

I’m getting more info since it got moved. There isn’t much in this section about 6.0. My mistake and thanks for your he.

I think I'm gonna go with this guy.

I shouldve mentioned earlier that I am going to add a blower to this truck after the warranty is up. At that point, I will add long tubes and an electrically operated cutout:

So I will have a quiet side and a wide open side with no muffler.

Hopefully someone will make long tube headers by the time you are ready for them. Nothing available as of now.

EZTundra77 · February 4, 2019

I also wonder about the noise levels/drone from long tubes. Obviously the performance potential is greater w/ LT's. My tundras and sequoia came stock with short tube Stainless headers and they are silent using the stock mufflers/exhaust. TRD True duals and a TRD cold air intake woke that 5.7 iForce up though. You could hear it had headers then. I havent touched the exhaust in the Sequoia yet. It has the TRD CAI which did actually deepen the engine/exhaust note but I will wait until the warranty is up on that also before I beef that thing up.

I want to see a vid after you get it installed. I want as much flow as I can but only a little more noise. I plan on a supercharger to once I quit spending some much on my diesel and can give my gasser some upgrades.

I tried the super 50 but took it off, the hwy drone was horrible, idle and throttle was nice but the drone at hwy speed was horrible, I couldn't stand it and took it off, its for sale with the band clamps and has the small extension welded on, its ready to bolt on. I wish it worked, I loved the idle and stomping on it sound.

I have the big Magnaflow on my 15.it sounds good and does not have a bad drone unless we are towing our big 5th wheel up hill and hard. At 4000-4500 rpm it drones a bit.

You have a 6.0 L? Otherwise stock or cat back kit? Which muffler?

My truck is a 6.0l.the whole exhaust is stock with the exception of cutting in the big Magnaflow. It was done in 2015 and I don't remember the part number but i do remember it was long enough on our crew cab standard bed not to need any filler pipe. It is 3.5" in and 3.5" out with an offset front at least. The body is large oval. It may have been the 12909 but I would have to go down the where it is stored and measure to be sure.

do you remember what series it is? Sounds like an XL chambered design

It measures out to the 12909 with the 22" body oval. It was not chambered I don't think. You could see all the way through it.
