Mufflers for Diesels

[NC_Mog]

Is there anything I should be looking for in a replacement muffler for a diesel truck? Is there any difference between one for a gas engine and one for a diesel? I'm looking for general info on this.



Thanks.

Go to your local NAPA and ask to look in their Heavy Truck catalog.

Mufflers of all types and sizes, prices are pretty good also.



Not sure if there is a difference for gas or diesel engines.

I am not sure of how accurate my source was, but I have heard that if you use the wrong type of muffler you risk it becoming plugged sooner with the soot that diesel produce. On a stock truck that burns fairly clean, you would probably be OK.

Good comment. The truck is stock, but I wouldn't say it burns clean. I can smoke with the best of them thanks to 36 year old technology.

I'm assuming the same applies to non-turbo applications. I do want to reduce the noise level I currently have. Some is radiating out from the engine itself, but the muffler sounds (and looks) like it doesn't have much muffling capability left.

Does anyone know where /who makes the shortest 4" flow thru muffler? Just curious.....

 

[lmills]

Check this out. This is the cheapest I have found. I used it on my 01 that I hand and liked it. Magnaflow also makes a really short one in their race series. I believe it's either 6 or 8"s long and stainless steel.

Don't use any type of muffler that is set up with baffles to capitalize on exhaust pulses or backpressure to work.



In other words, don't use a Flowmaster.



Straight thru styles are the best for turbocharged diesels. Glasspacks work, too.

Dan is correct here..... Dont use any chambered mufflers on ANY turbocharged diesel engines. The turbo removes the pulses out of the exhaust anyway and it would be detrimental to performance. Correct muffler to use in turbo'ed applications is a straight-through design. Many good sources have been posted already regarding where to find em.



---- of course there is the option of straight-pipe.

I used to run a glasspack on this truck, as well as my 91 CTD... . Loud is IN!!!!!!!! haha

Thanks for the input. I need to do some searching. I don't need a glasspack... while power would be good, I need noise reduction. I get plenty of loudness; I already were ear plugs in the truck. The cab, fiberglass engine cover and softtop don't do anything to attenuate the noise.

turbo mufflers

Straight through mufflers are not the only ones to use on turbo charged mufflers.



I prefer a good turbo muffler. Performance is plenty good for a street machine, and they sound good, a little quieter than a straight through design.



I've never seen one clogged with soot.

Mufflers ???

Don't need no stinkin muffler













w/ just a resinator alone it should have a nice tone too it

min. reverb in the cab

Where does one get a 4" inlet/outlet resinator?

I had a chambered-turbo muffler put on my truck to cut down the noise (not the truck, the noise of the neighbor :-{} ). I noticed an immediate loss of power and fuel mileage. When accelerating I could only get 15lbs of boost although I touched 16 once or twice. I also had a best tank of 16. 5 whereas before I was getting about 18. 5-19. I went today and installed a glasspack in place of this thing and I can't believe it's the same truck. I immediately noticed more power and quicker turbo spool (I hit 15 under light acceleration with a max of about 18). I can also get a good bit of smoke now under hard acceleration. Sound level is very reasonable as well. IMHO the glasspack is the way to go.
