the system sounds very good, the only problem I had was the exhaust clamps didn't come with nuts. I had to go out and purchase some.

I was surprised of the nice deep tone of the little 4.7 L in my Sequoia. I am very pleased with sweet note and rap when put my foot in it. The instal was easy and fit is great. Very happy.

Looks and sounds great. I had it installed by my mechanic for approximatly $200. Haven't had it long enough to see a difference in mileage but definitely feel a HP improvement.

Great Value

A fair price for a great product. A little research unveiled that a larger competitor was using cheaper steel in their product and was approx. $300 more. This is my first aftermarket exhaust so time will tell. I have experienced increased horsepower, better gas mileage, and a great growl. I only wish I bought the dual exhaust! Thanks, Dante
