Kit arrived in a timely fashion, undamaged. EVERYTHING was there, every screw & nut. Directions were quite clear; took about 45 minutes to install.MUCH improved acceleration, with a good, throaty roar!! But I was pleased with the increase in gas mileage,almost as a bonus!! I highly recomend this product, not just as a performance upgrade, but as a mileage booster, too!
