i just bought a new 2006 ram 3500 quad 4x4 dually with the cummins, and i wanna change out the stock muffler for a more flow through sounding muffler, hit me with suggestions

 

I just put the Aero-Turbine 4040L on mine. I like it. Not too loud, but a good rumble especially when you get on it. No drone! So far I have seen about a .5 increase in mileage. I shopped around. I was quoted anywhere from 375 installed to 250.

 

I just put on a magnaflow 4" muffler, sounds great not to loud and no drown. cost about 145 bucks from summit shipped. I have a 06 quad drw 4x4 manual.

 

Is it a real noticable difference, deeper, lower tone?

 

shuttle worth is a canadian company that specifically designs mufflers for diesel engines. I love mine. good sound, no drone, can feel a good difference, 2 and change installed

 

I am another vote for Magnaflow 4''. Quite a bit deeper tone than stock. Not loud or annoying, but definately some louder than stocker. No drone. Can really hear it when under an overpass and get on it. My kitty ran into the garage. The truck "purrs" just fine without it.

Also, the EGTs seem to run cooler now too (maybe 100-150 degrees).......but i added an AFE Stage 2 air intake at the same time so i don't know what made the bigger difference.

 

I am looking into the 4" Magnaflow and an air intake. Will these minor mods affect the warranty?

 

I vote no muffler! But that's just me

 

Donaldson 40".$65, no drone, deeper tone but not loud. When I first installed it, I couldn't tell much of a difference. But now that ithas been sooted up a bit, it has a good deep sound. Not really louder, but deeper. $40 to install so a total of $105. You get it at a big truck acc. shop.
