I love this easy installation and the whistle sound is great. Can really feel the torque power on the highway great investment.

have had this on for just a few days and noticed a very distinct 2 miles to the gallon better on a new tank of fuel. there is a whistle but i like it. deeper breathing for the engine. this is the 2nd grand cherokee i have had and it is the same result as before-good product!
