Just bought an 04 duramax and want to know where i start doing upgrades. Dont have a ton of money to do much yet but just want to know whats out there. My truck has 160k on it
First thing I did was straight pipe it.the EGT's will be cooler,and the sound and MPG is slightly better.Getting that 3.5 inch opened up will hold you for a mid level tuner..I run a PPE and the 3.5 does fine,I ain't saying I couldn't benefit from 4inch,but hell I am tight and old fashioned...sometimes.:drink
