01 Cummins 5speed
 

I just bought my truck last fall and i am finally starting to get into the upgrades. I already have an AEM cold air intake on it, plan on ordering a Smarty and MBRP stainless 5 inch exhaust. Am I taking the right route to performance upgrades? any suggestions thanks

Not sure how many miles are on your truck, but i'd start lookin at an Air Dog or Fass fuel system before your lift pump fails and possibly burns up your injection pump.

i have roughly 140,000. for the time being i have a replacement lift pump on it by BD Diesel, i plan on getting an Air Dog next year before i start getting into the injectors and turbo.

Well then i'd say your on the right track so far

Do you have gauges?

Honestly 5" exhaust is a waste of money. If you need new just get 4", its plenty big.

X2 on the exhaust. and before you start getting to carried away on ordering a smarty or any other programmer/box GET GAUGES! cant stress that enough and im sure everyone else on here will tell you the same thing. gotta know where everythings at before you get to carried away:tttt::5:

the 5" will have trouble fitting witht he stock turbo and the fire wall. Get the 4". Auto or manual? Repalced your lift pump yet?
