Excellent product. I installed this with the Saab Sport exhaust. The sound is just wonderful, loud and throaty ( but not obnoxious) on WOT, when cruising at hwy speeds you cannot hear it. Excellent craftmanship, fit like a glove. Turbo lag is reduced greatly, especially in higher gears, I saw a small increase in fuel mileage. You will drive with your windows down all the time.
