Hi guys, I had a 96 ZJ 4.0L, tranny wasn't shifting right, running kinda rough. I had a Dynomax catback system on hand, so I decided to install it before I got to the other problems I was having. The other problems disappeared after the Dynomax was on.
The ZJ is history thanks to rust.
Now my ride is a 99 XJ 4.0L. Mileage started going down to 14 - 15 mpg, with sluggish performance. Went and installed another Dynomax catback on it and everythings back to normal again.
Don't know why this is, or if it's just my rides, but thought I'd share this with other members here. 4.0L Jeeps really need to breath I guess. And no this ain't a dynomax commercial, it was the cheapest system available
