i have an 03 bone stock cummins diesel (not High ouput) and im looking to do a willys whistler intake and a 5" exhaust... no programmer for now but im curious of how much rear wheel HP I should expect with these two mods....also my 03 didnt come with a cat did it? i guess i can just look under the truck when i get home but it is a california truck and idk if they did anything different for emissions...

03 Cali truck will have a factory CAT. Wont gain much with the intake and exhaust untill you go with a programmer. It will help lower EGT's.
