Okay, after driving it on city streets and the highway, my verdict is in...I LOVE THEM!
However if you're getting them, you should know that they do add NVH. But if you close your eyes while the engine is running, from the inside of the car it sounds like a mustang with a quiet Magnaflow exhaust, except there's no drone on the highway. I love it..AND it's actually no louder on the outside of the vehicle. It has actually given me a heavier foot...
As for the "feel", again, they're fantastic! I love the connection to the drivetrain. If your engine has a miss, you'll most likely know it before you get a warning light.
Another thing I've noticed is that the car no longer rolls [what feels like] 2 or 3 inches after you take your foot off the brake in Park. It's now more like 1 inch.
If you don't want NVH, these may not be for you....but I love mine! Thanks Anthony!
