Thats some ricer crap. I have an Xlerator muffler that has a built in X pipe and it sounds good to me. Lifetime waranty also. Much smaller than the stock oil barrel that was on there. Straight through design and di/do. Cat back would be best but more bucks. I have a deep sound without the cost of cat back. Well worth a try. When and if I ever get headers, I'll go with a whole new system.
