Awesome little power pack! Very user friendly and easy to do. Not just more power at WOT but tighter shifts and better with just moderate throttle increases. Clears the annoying back pressure codes that come up with an after market exhaust. Noticeable difference for not much out of pocket and nice addition to intake and exhaust upgrades on this 6.4 SRT8 Jeep.
