I just purchased my first diesel. 03 2500 and it already had a k and n intake and a few other little upgrades. I was rear ended and had just a little scratch on my bumper. Well my $500 check came from Allstate for repairs and I could care less about a paint chip on a bumper. So I am looking to get some more mpgs out of this beast. Should I upgrade my 3.5" exhaust for a 4 or 5 in? Or buy the smarty jr? Which is the best bang for my buck right now. I don't haul much yet being winter and most of the wood is already stacked. Being new to diesels I don't want to mess it up.

 

I'd get rid of the k&n for an amsoil dry filter, then a smarty if you don't care about sound

Yeah I don't care about what it sounds like.

 

Ok, the k&n is supposed to be terrible for these trucks (oiled filters in general) so the dry filter with a pre filter is great since youve already got the piping, then a smarty will give you a nice boost in power and some more mpgs

Ok, like I said this is my first diesel and I will check out the amsoil filters

So the pre filter is like a thin mesh bag that goes over the dry filter correct?

 

Any dry filter will work, amsoil is just one I've seen alot while lurking the cummins forum

Do you have any experience with a smarty jr?

 

Not personally, there is lots of info on them, haven't seen much here, but tons on cf

alright, so I bought the smarty jr and it should be here tomorrow! I am now going to try to figure out what kind of tranny upgrades I need so I dont fry it.
