I'm wanting to replace my muffler with a universal one from Magnaflow. I've narrowed my choices down to Magnaflow #12589 or Magnaflow #12259. I'm having a hard time getting a feel for how loud each one would be. I want something louder than stock, but not something that when I start the truck everyone looks. I'm really wanting one that sounds great just at idle and is loud when I really get into it but somewhat stock-ish just driving. I've listened to clips online of both but due to different types of recordings and how they were recorded, I can't get a feel for it. I plan on ordering the muffler online (PerformancePeddler.com) because I can get it much, much cheaper than my local shop can order it for me. Anyone hear both? Or at least have one or the other and can give me some feedback? I'm also still torn on what Magnaflow exhaust tip I want. I'm guessing Magnaflow #35113 but am not entirely sure it'll fit I guess. I'm guessing something about 10" long and about 3.5" in diameter but I'm really not sure what will work. I'm wanting the exhaust to exit the same place as stock. All I plan on doing is swapping the muffler and adding the tip. So, can someone help me? I did a search already and that's how I got it narrowed but I found no side by side comparisons. Thanks for any help, I'd really appreciate it.

Well Magnaflow in general is really quiet, you have to be WOT to hear it roar, I'd say the 18" though. 22" might be quieter than stock at idle.

i went with the 12589 and am pretty happy with it. below 2k you cant hear it unless under load. cruising ont he highway its no louder then stock until you go over 2k rpms. it sounds nice with a deep rumble when on it.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
