Im in the middle of a 4mil build. I'm almost done. I went with CPI's. I had my cylinders ported so it works best with my over all mods, riding etc. I didnt settle for a generic dune. trail or play port etc. You should talk to whoever ported your cylinders to see which pipes performs best with that you have in mind. IMO that's your best bet.

I would run CPI's as well. The 4 mill is going to gain you some mid range. The cpi's will allow your engine to rev out better than T5's or other general use pipes.

 

I run them on my FAST 4 mill Dune port.

 

If you want super nice chrome then get them from cascade. They cost a little more from them but they have a way better chrome job.
