upgrades. Also are you doing a dyno before and after to see the results? I have everything else 2.5" with a 3" exhaust just wondering what to expect with the installation of the planer piping to complete my full intake system. Greg D. stated I could install at a later date so I have started the research. Thanks and good luck with the install. I am about to go do a boost leak test and change the oil and I can take a better look for myself
