diesel muffler on gas motor?

fastdurango00 · Oct 9, 2009

would you gain any performance out of it? or would it just be pointless?

bogieboy · Oct 9, 2009

Sounds pointless to me...a muffler is a muffler...don't really see what the difference would be....all it does is muffle the sound and provide backpressure for the engine...

I am assuming that diesels have a varying amount of backpressure when compared to gas engines.

That's why Jake brakes work on diesels, but not on our trucks.

Jake brakes are different than exhaust brakes (exhaust brakes are the only kind found on pickups). The reason diesels need the help is they do not have a throttle valve like a gas engine. So an exhaust brake is the oppsite of a throttle valve, it is more effective because restricting the exhaust flow slows the engine more than restricting the intake (vacuum vs pressure). An exhaust or jake brake would actually work on a gas engine but there isn't as much of a need for one plus to actually make it effective the throttle would have to be opened, complicating things.

A mufler is a muffler. A "diesel" muffler is just a muffler with a "big" inlet/outlet.

You're probably thinking of the sidewinder truck that is really fast and has a diesel engine, lol. Really fast is an understatement.:jester:

that would be me. there is no difference, just bigger.

fastdurango00 · Oct 10, 2009

so, what your saying is that the flow of a diesle muffler will be the same as the stock muffler i currently have?

Ok. I knew it was a badass truck, been a long time since I saw the exhaust pics:mullet:

not even close.

all a diesel muffler is, is a larger (inlet/outlet & body) version of a said aftermarket muffler.

i.e. these are essentially the same muffler

diesel muffler being a muffler from a ram 2500, would it flow better or worse? i ask all of this because im wanting a better flowing exhaust, but i dont want the loudness of it all, i want to keep it looking and sounding as stock as possible so when i roll up on some fool and then smoke his ass, he is dumbfounded and left eating my dust...

You can buy a high flowing performance muffler that sounds stock it just has to be bigger than what most guys run. You can get like a 20 something inch magnaflow and it will sound pretty much stock.

Like Y2kota's setup:

I ran a 45" Thrush glasspack at one time, sounds good and not to loud. Much better then any stock set up!

Running a Diesel muffler is kind of silly! Like mentioned before, it is just bigger, but does flow better then any stock muffler do to size.

There are alot of options you can do. Even a cheap replacement is better then a stock muffler(flow wise)!

I would not run one of those 4 inch( or larger) inlet/outlet systems..
Gas engines like a little back pressure..
And its not great for your valves..

not necessarily true, it depends on the engine. These magnum v8s are bit different. It seems that can't go too big on the exhaust or intake tracts, with the mgnum v8s.
