The most popular combo is the ER Pipe with Tial BOV, as the HKS is a very loud BOV and most don't want it loud, but the HKS is great if you want a loud BOV. The Tial is pretty subdued and a more refined sound.

Now if you don't want any sound from the setup you can upgrade to Forge DVs. Now with the Forge you don't need a new charge pipe as you can use your stock one, but its still something I would upgrade, but if its not in the budget you can do it in two steps, get the Forge DVs now and Upgrade CP later.

With a BOV you would need a new charge pipe bough with the BOV.
