no muffler

Interesting that the 3g makes a lot of noise w/o the muffler. I had no muffler on my 96 and liked the minor increase in sound. Seems like most don't like no muffler on the 3g?

i heard our trucks sound like ricers with no muffler

For me it's just that at a certain RPM range, around 2300, it makes a loud vibrating noise that resonates through the cab badly.



My race bullet is on the way so hopefully that will fix the noise.

I finally found a straight through muffler that is a direct replacement for the 04 stock muffler. Brand name is FULLBOAR.

The overall length is 36", It is 3½" input and output. PART# is SD817

They have a website fullboarexhaust.com

This is a BIG muffler, about 9" dia.

I briefly had a straight pipe on my 2003 and it sounded terrible! I then put on a Rip Rooks 4" exhaust system with the straight through muffler. It sounds better, but still not as good as a straight piped 12 valver. I have heard some good sounding 24 valve 1998. 5-2002 trucks. Is it the new fuel system that makes the difference? I sure would love to have a 4" straight pipe system and eventually plan a dual stack/flatbed conversion, but I want it to sound as good as my 1996!

With injectors and an EZ my trucks 5 inch system sounds like a big rig...

 

[CATCRACKER]

the ez changes the sound of the truck in that you get through the rpm range much faster which does indeed have a much better sound. the pilot injection is what is messing with the sound. i cant wait for variable vane turbo that is when i will sell this trck

 

[Fred Swanson]

Add a turbo and the rushing air sound is gone, like Greg said, the right 5inch setup will give it a definite big truck sound.

i tried to remove my muffler before the snow hit the ground but it proved to be stubborn. the factory tightened them clamps up real good crimping the pipe enough that i could not get it out without cutting so i gave up on it for now... the muffler won that round, but when the nice weather comes around again, it will loose... and will be disemboweled :-laf :-laf

NICKleinonen, Where the clamps were, did you try to heat the crimped areas with a torch? If you heat it up till it glows, then you can wiggle the pipe and it will come off, me thinks

 

[JHardwick]

No, nick leinonen, is right about the crimps. I had to split the outer tube before getting the muffler out. After the muffler was gutted, I had to weld the slits back up in order to re-clamp the system.



It's easy if you have the equipment, PIA I'm sure if you don't.

Thats what it sounded like to me. I cant understand why anybody likes it but to each his own I guess.

 

[JHardwick]

This is only a guess because I have nothing to compare against. But, I'm thinking that a hollow chamber the size of a 55 gallon drum sounds different than a straight through pipe. It sounds pretty throaty to me, not as load as the older trucks, but definitely diesel.
