Hey Guys/Gals, Looking at doing a Cai and tune on my '13 GT. Anyone done this on their '11+ Coyote ? Which ones would you recommend, and which ones would you avoid. Currently looking at the JLT + Bama combo from American Muscle, seems like a decent price and good reviews on their website... Also wondering about the finishes, there are stainless tubes, carbon fiber tubes, and just plain black tubes, are any better than the next, or just a engine dress up feature. Thanks ! Jaret sorry if this has already been visited.
