Does anyone have a high flowing 3in muffler that is quite. I have dual 3 in 40 series flow masters with headers and my truck is pretty loud.

 

get the longest magnaflow muffler you can find. probably like a 28" case or something.

 

+1 the longer the muffler case the quieter it is...

 

yes, the long magnaflow muffer will do the trick.
we just put one today on my buddy's 2500 6L ecsb and it's barly noticeable.
it's 30" long and it has a nice quiet tone.

 

Check out the .mov's here. That's what it sounded like with my 4.8L

here is mine magnaflow

 

magnaflow part# 12579?Ithink?... I believe its a 22" case, one of the biggest one, has a real little rumble with no drone!!! I have it on my truck with no cats and I cant believe how quite it is... I believe its the same one v8 and ranwalk is running, check the southern section there is a video of ranwalks exhaust...

 

i have one of the longer magnaflows and its pretty quiet
