First off, the SS system was cheaper than the aluminized one! Great offer! The package arrived in excellent condition, all equipment and instructions are present. I installed the system myself in 3 hours with no difficulty including removing the old exhaust. The only issue I had was one of the clips that came with the kit broke, but that was easily fixed with a better replacement at the parts store for a few bucks. All in all this is a solid easy to install kit that offers a good Ford V10 setup. I had trouble finding exhaust reviews for the Excursion and am glad I went with the Gibson kit. Sounds great for a V10 in my opinion as most people have complained about the exhaust from the 6.8 liter engine. But not me, you must understand that this is not a V8 and the kit makes the exhaust a little louder than stock. This is a cat back kit that won't weigh on your wallet and gives you that good ol' feeling of glad I decided to buy it. The drone in the cockpit is minimal and only occurs around 1500-1750 rpm or around 50-55 mph on my Excursion. The kids said the exhaust didn't bother them or distract them at all in the third row of seats. Gibson has a name for the quieter side of the exhaust and that's what I wanted and got from them. Don't think this kit is ineffective because it isn't. Great handling, sound and looks. Thanks Revain and Gibson for a great offer!
