2004 Maxima 4 seater automatic , i need to replace both catalytic converter the ones close to the engin I'm ordering the Magnaflow ones and I know one is 50833 but the other could be one of two 50809 or 49322 I called them and they say 5 or 6 speed I think I would be a 5 speed and the one should be 50809 anyone have info on this

 

 

if yours in an auto then it'll be a 5 speed. Why not go with racingline high flow cats?

 

If you're 2004 SL you could also be 4-speed. Confirm.

 

yes that would have been the thing to do but I will keep it in mind for the some better air flow later on , what about body parts grill stuff like that whats a good place for stuff like that has to be in canada

 

Its a SE 4 seater would that make it a 5-speed

 

Yes.
