Planning on going K04 in the next week or so. I was given a quote on a CTS kit that I cannot turn down. However, I am cannot for the life of me get @CTSturbo to reply to my question of having the HFC made to fit. So even though I have asked in a couple of threads to no avail, I want to reach out to the masses. Has anyone ran a CTS K04, CTS HFC and modified it to work with an APR Turboback Exhaust?
