I wanted to know if anybody knows of a louder 4" muffler than the Banks muffler I have now? My brother put a straight pipe in his, I don't want it that loud though.

I was gonna say strait pipe but you say that too loud. I think DPP might have something. I know the banks is really quiet.

I like the sound of my DTT. Initial "dump truck" sound upon accelleration turns into a slightly hissy, but throaty note. Good turbo whistle too. I have mine on installed in the "quiet" orientation.

dyno max race magnum is bout right if you dont want, straight pipe. it pretty much takes all the "bark" out of the exhaust but still has a very good sound to it

CTD_Neil

thanks guys, i'll take a look at your suggestions. I wouldn't mind something a little barky, just not the straight pipe sound.

The Dynomax Race Magnum Bullet is only $35 through Summit, may have to try it. ANy drawbacks to running a muffler that is much smaller body diameter than my current Banks muffler which is huge?

Get the Dynomax round not the bullet

CTD_Neil

what is the difference? Is the round quieter? or just better for a diesel application?

ramcummins

The bullets seem to be a little more "ratty". Where as the round gives it a deeper sound.

CTD_Neil

cool, i think that would be better. Twice the price though

ramcummins

Well worth it

You might consider replacing the Banks muffler with an Aeroturbine which has a nice throaty engine sound. Also when the Aeroturbine is installed as far forward as possible it can help lower EGTs noticeably.

How loud is this Aeroturbine muffler compared to the Banks? How quiet compared to straight pipe?

Car_nut57

Tough question. Inside the cab if the Aeroturbine is placed under the passengers feet as far forward as possible its not much louder than stock, but a much deeper sound. Out the tail pipe louder than Banks but not as loud or raspy as a straight pipe. the sound file on our website will give you some idea of the engine sound from the tail pipe produced by the Aeroturbine, but its hard to get an idea of loudness from an internet sound file.

I'm running the aeroturbine and really like the sound. It is almost straight pipe loud, but without any drone. I think you would be really happy with the sound you get. its sort of unique, compared the regular flow-through mufflers
