Also installing Magnaflow Catalytic converter and Kolak 3" tailpipe using V-band clamp to fasten it all together. I would also recommend replacing the front right O2 sensor if you haven't done this because it is impossible to change without removing the upper control arm. For 99-04 Jeep Grand Cherokee with 4.7 V8
The wheels are by OE Wheels, 20 Inches, they are a knock-off of the SRT wheel. There is an Amazon link below.
