Comments: Bought this product for my XJ. My stock Cat went out so I decided to replace everything, boy was I glad! It makes my jeep have a nice rumble sound at high and low stead speeds. Not too loud though when you step on it; wish it was! Overall it makes the Jeep sound better than stock at a low low price. It IS worth the $$$$$.

If I have to I will buy again!
