I've got one and I'm always singing the praises of it. It gives a little power boost at high RPMs and sounds great. It's quiet at idle and normal driving, and screams when you floor it. Not a bit farty, no matter how hard you try. It has a deep tone and when you're hitting 4K+ RPMs, you car sounds like a F1 race engine, not a lawnmower. You'll be very satisfied with this exhaust if you get it.
