Currently running a couple of aftermarket "things" from previous owner that do little to cut noise, and boy the resonance inside the cab is unreal.

I need to buy a muffler that won't restrict too much, and be quiet.

Any thoughts?

Thanks.

 

Some ideas:

I like the construction of the DynoMax Stainless Steel UltraFlo mufflers, and by trial and error have found that their longest one (36 inch long, 6 inch diameter model for RV use) in the regular muffler location and another 16 inch long UltraFlo as an exhaust tip makes for a quiet system that is also low backpressure.

For 2nd opinions, read what these guys found:

I also think these muffler designs are interesting:

I also wanted a quiet muffler. I installed a Walker cat back system with the Quiet Flow3 muffler. Even though it is a stock replacement it sounds really good. I'm so glad I didn't buy a performance muffler. I don't race my truck so restriction is not a problem.

 

walker is a good muffler and flows well... im thinking going that route and droping my flowmaster....

 

Great lots of info here. I have a 98 ram quad cab with 176000 kilometers, with the original exhaust system, but it won't be long now, the muffler is looking ripe.

Thanks Kayakman

 

Thanks for the replies and the info!!!

 

I have a Dynomax Ultra flow outside a deep and very mellow note , while inside nothing

 

DYNOMAXX!! i had one on their as my first mufffler. Im telling you, you're gunna love it. It is very quiet but if u step on it, sounds agressive, not realllly loud but loud enough.
