Get Rid Of Std Ram Muffler?

[JSkalet]

As you can see, I have a new 2001 6 Spd high output diesel. I've noticed that most of you have installed an after market muffler. Is the standard muffler significantly resistant, are the aftermarket mufflers straight thru and are they much noisier than stock? could you make a recommendation as to which one I should buy. thanks john skalet

Invest in a piece of straight pipe. Will not be a lot louder and you will get the most bang for your buck.

The best aftermarket muffler is the invisible one!

john, i guess i'm not a real man after all. i tried straight piped. the volume of the sound and the "dreaded drone" were too much for me. i then put the resonator back on. still too much for me. i now have a 4"system turbo to tail, with a long straight thru truck muffler--Goerlich's 3653. nice deep tone, not much if any louder than stock. i don't have any drone. i think that if you go with a 4" system, you will want a big, straight thru muffler. i'm not sure it makes any difference in performance, except to perhaps drop EGT.

Working around noisy diesel farm and heavy equipment most of my life I don't like my personal ride to be loud. Tried straight piping it when I removed my cat, forget that noise. I added a Banks free flow muffler it sounds almost stock, not louder just a deeper tone. Walker and others make similar mufflers. I don't feel there are any power or backpressure issues with a stock muffler as long as the rest of your engine is stock. Once you start bombing then it's time to change the exhaust system.

Out of 10,000 members, five have answered in the affirmative to your suggestion. That ain't hardly - THE MAJORITY.

I am straight piped and it is too loud for me. I do not have any resonance issues with mine, but I drive around 100 miles a day. The noise gets old driving that much. If I drove less it would be fine, go with what fits what you do with the truck.

thanks!

once again, thanks for all the great feedback and so prompt as well! john skalet

I am with illflem on this one (even though he does not like us 24 valvers). I waited 50,000 miles to put ona straight through desigh walker 21470 (3 1/2 " I. D. x 30" long). I am more than plesantly suprised by the lack of noise (just a lower tone) and increased performance.

Did a little surgery on the stock muffler

I just got a small cutting disk from the hardware store. Took the muffler off. Using a drill I cut and bent the internal restrictive area out of the way and put the muffler back on. It's not quite straight through but I think it flows a lot better.



From what I could tell, the stock exhaust flows all the way to the back of the muffler to a rear chamber, then all the way back to the front chamber via two smaller pipes, then over to a fourth pipe to go down the muffler again and out the back. In some places these internal pipes had small holes in them about the width of a toothpick. I suppose a little exhaust would flow through those little holes as well. The exhaust has to take this route because all the pipes are suspended by two solid walls at the front and rear of the muffler.

Now my exhaust goes in, makes an immediate left then right, and straight out the back.



The reason I did all this work is because I was trying to decide what I wanted to go buy. If you already know what you want then go buy it because this was a lot of work. After messing around with the stock muffler it ended up being perfect. So I just kept my money. However, doing it yourself is to much work. I took this route because I wanted to be able to go back if I didn't like it. But I got real dirty. I was pick'n particulate matter out of my nose for a week!

The stock muffler isn't too restrictive if the engine is stock. Restriction goes up as power is "enhanced. " I have used the Walker straight through mufflers with perforated core; the 3" #21468 is much quieter than straight pipe but still kinda noisy as the core is only about 21" long. The bigger 3. 5" 21470 and 4" 21471 have about 30" cores and are quieter. Your stock system should have 3" headpipe feeding a resonator with 4" outlet and 4" inlet muffler with 3" outlet and 3" tailpipe. So, if you want about zero restriction for up to 350 hp applications, the easiest but not the most quiet is to buy a length of 3" pipe expanded on one end, skip it over the head pipe, into the 21468, and put the tailpipe into the outlet of the muffler.



Don't listen to these guys as they are all b. o. m. b. ers and love power and noise. Of course, my sickly Ram is all stock--everything was in stock when I used it
