A nice, QUIET muffler? do they exist??

[david85]

This would be fore my Dad's truck since he perfers a quiet ride even if it sacrifices a bit of performance. No, we won't be straight piping it

The muffler it has right now may be factory original but I'm not sure. It seems to do the job but everything from the muffler and back needs to be replaced. The straight through muffler I have on my truck sucks plain and simple (killed the turbo wistle, an still drones in the cab to give me headaches on long drives - seriously, the sound inside was completely unchanged after adding it to the straight pipe setup).

I realize this can be considered blasphemy, but does a nice quiet muffler exist from an aftermarket supplier? Generally they all claim to make it "sound better" and increase performance

Walker makes a muffler called the quiet flow.

From what I recall they have a stock sound but are high flow mufflers. I don't have any actual experience with them but recall seeing a video comparing them to others some place on the web.

Put a 4" exhaust on the thing and slap a 4" big truck muffler on it. shove the longest one that you can fit under there between the 4" adapter and where it goes either over teh axle or out in front of teh tire and it will sound quite civilized. I put the shortest one I could get on mine and it still is basically quiet. Theres quite a bit of insulation packing in those things.More than in a stock muffler, but without the restriction that hinders performance so badly

A turbo makes a fine muffler

Its a 6.5 with factory turbo, so thats already covered....

Thanks for the suggestions, I'll look into that.

They sure do make quiet mufflers; they came factory-standard on 1989-1993 Dodge/Cummins; 3-inch inlet/outlet and STAINLESS.

sound proof the cab instead? just an idea...

My truck has a solid inch of carpet and cotton matting in some places of the floor. My problem seems to be with a low pitched resonance at certain speed/RPMs. Never heard his truck without a muffler or a "performance" muffler, so I don't know how bad it would be in his case.

one of the biggest factors in how loud an engine is the length of the exhaust system. i learned this years ago when i had my Jeep. it had a 360 in it with headers that dumped out the side and 2 glass packs running right under the body with a simple 90 out right behind the door. several people burnt there legs on it and it was load as hell. in an effort to quite it down i tried going from glasspacks to turbo and regular style mufflers. i ended up with simple thrush turbo mufflers on either side for a while.

i later got tired of riding down the highway with a barriar in the middle to bounce back all the sound and saved up for a full exhaust. still being freshout on my own and cheap i had the guys doing the work re-use the mufflers. with full dual exhaust out the back my Jeep sounded about the same as any other V-8 vehicle.

same mufflers differant exhaust, but the sound level was night and day. just some food for thought, even the piping has a muffling effect.

>>> YOU CAN HAVE THE BEST OF BOTH <<<

Way back in old-timey days, we would install cable-operated exhaust cut-outs just behind the headers and a really quiet normal exhaust system all the way back.

One thing I'm coming across is 'resonators' (seriously, I know next to nothing about mufflers ). I'm reading that they can kill the drone in the exhaust if placed before the muffler - is that correct? or is that a subjective situation from one vehicle to the next?

No, they really do quiet things down a bit...alot of the newer trucks use them (gas trucks) For instance, a Hemi powered Ram 2500 can have up to 4 of them. Basically they just create a chamber for the exhaust gases and noise to bounce around in and against each other.

I'd look for a factory exhaust off of a late model Powerstroke. It seems everyone is rushing to install a flashy aftermarket exhaust on those trucks, and someone would likely GIVE you the old factory exhaust if you took it out of their way. The modern trucks have a nice quiet muffler and tailpipe section that can likely easily be modified to fit your older application.

For what it's worth, I have a MBRP exhaust kit on my truck intended for a Powerstroke, but it fit with minimal modifications.

So thats in front of the muffler? or does it have only resonators?

I don't know any powerstroke guys around here but wouldn't mind paying for a new one since the front half of his exhaust is already stainless steel (I put that in a few years back).
