I'm sick of the noise, so I'm looking for ideas. I have a 3" magnaflow exhaust w/off road y pipe and pacesetter LT's. LS1 with a cam and ported heads so it's pretty loud. I'm looking to quiet it down by replacing the muffler. It currently has the 5x18 (22" overall) stainless Magnaflow muffler. What would be a good replacement muffler? I'm considering a Dynomax super turbo, I know those are quiet. What else is there??

Saw this. Good info in that thread.

 

I have the 22" case magnaflow with a 12" by 7" round magnaflow in front and it's pretty quiet. Has a slight rumble to it outside, but nothing inside. No drone or hum.

 

Also look to the VT muffler as well.

Put a Dynomax small 3" muffler inline with yours. Sounds quiet at idle but sounds mean when you open it up.

 

Id like to see someone use the flo pro 8880
FLO~PRO - Heavy Duty Specs

 

Ordered a Dynomax super turbo, we'll see how it goes.

 

I think that the super turbo is a great choice for something pretty quiet that will still flow pretty well. I would have one on my truck if they made one in 3.5".

 

Bola pro xs is a good quiet muffler.
