AGR - as one of the only other HSM exhaust owners, I agree. The axle-back straight pipe is great, and still sounds Saxay when I pull into the ol' 3-level parking garage at work, but it does get a little onorous at times. I've been to the Dealer twice in the last month so I'm pretty good at installing/removing it, have it down to 13 minutes from "walking out to garage" to "clean hands eating a toll-house cookie". UN-fortunately, I don't think I can do it while awake, since the last 2 times I've installed the stocker it was BEFORE going to the dealer (like before 6AM...)
Does the CAI really make any difference other than sound?
Have fun in the garage...
