picked one up at a junkyard. welded it up sounds amazing how do i tell what series it is? there are some codes on the muffler but i dont know if that will relate. anybody?

 

Try the Flowmaster "tech line" @ 1-800-544-4761
They should know if nobody here don't.

 

Shy of cutting it open there is not reall any way to tell. More than likely it is an original 40 series though.

 

i have 40 series and she purrss man....thats what i recommend

 

maybe it if you knew what it came off of, but i'm no help anyways I duno what one it is?

 

92 nissan H.B. 5speed. but i doubt that is going to matter

 

Nope, if flowmasters were application specific it would help but they are all universal.

Is the muffler silver or black? Is the case 14" long? what size inlet/outlet? what is the offset of the muffler? I have my flowmaster catalog right beside me... maybe I can try to narrow it down a bit more.

 

need some pics.
