which muffler gives off more interior noise? the super 44 or the 40 series american thunder?

 

The 44.

 

i think there the same

 

I have tried both mufflers, and I can personally attest to the fact that the Super 44 is noticably louder than the 40 series. I really enjoy both mufflers. If you don't like any crackling, then the Super 44 is not for you. It likes to crackle a lot which I thought was pretty neat. The 40 is smoother, but I think it's a great sound too.

 

supper 44

 

Probably the Super 44.

 

what kind of sound do you want?
