Just keep in mind there is really no correct way on what you’re doing, after all a cummins in a c series truck will never be “correct.” Now on that note you can go wrong on things, but as long as you don’t bottle neck the charge coming from the turbo to the intake you’re fine. My setup is an he351 and comes out 2.75” to a 3” pipe, 3” in and out duramax intercooler and then a modified P-pump intake horn. Silicone couplers/boots are available in many different sizes and step ups. I found the p-pump horn with a 24v plenum plate was the easiest way to clear the brake master cylinder.
