When doing over 40mph, I need to give my V8 Grand cherokee almost half throttle just for a simple kick down. Transmission shifts perfectly, but the kick down is annoying.

Also my cat is running red hot, wonder if a fried clogged converter causes this also. Thinking about replacing cat.

For your exhaust problem, do what I did, buy a new cat and put on the new cat with some dual flowmaster exhaust. With a 5.9 I wouldn't have anything else. I have a 5.2 and trust me, it sounds sweet just idleing so imagine it going down the road.

mikieem, where did u get ur Dual Exhaust and what kind is it..
