I have this setup and love the idle! I also have long tubes, cat delete, x-pipe, and flow master “Super 44”(dual in/dual out) which obviously weighs into the sound coming out. I tried briefly to add a video but I’m new to posting on here and got frustrated before I figured it out. Richard holdener from Westech has a YouTube video where he runs 4 diff. cams in a 6.0 and the results are impressive for this cam on the Dyno. I believe it was called “mild to wild”. So imo you get the best of both worlds: the idle sound you crave and a healthy boost in performance. Just wish I was more tech savvy and able to post the video!
