The other day I ordered the PowerMaxCR and 4" SS MBRP exhaust... . From the searches I have done, I am going need a larger turbo and a better clutch. I have already picked out the clutch I will be getting, but I need to know which turbos are "on top" right now. From my understanding, the two best choices are the Super B, and the B1... . What are the differences in the two? Which one is better for the longevity of the truck? Do they come with warrantys? Do these turbos sing as loud as stock? Thanks for any and all information pertaining to upgrading turbos
