Install sucked, but no pain no gain
Tolerances were very tight. The collector bolts provided were way too long so I just used the original ones. Installation was closer to 4 hours rather than the two the instructions estimated. Now that everything is installed I can say I'm very happy with the results. I've only put about 50 miles on them so far but I do notice a little better throttle response. They do look awesome, especially with my 6" lift. You can see these bad boys right through the wheel well!
