I installed on my 2005 Cummins 5.9 Diesel and it was a very easy installation if you have common mechanical sense. The instructions are well.... ehh. But if fits great! Turbo spools much quicker making drivability much better, once you're in there you could take out your turbo silencer ring if you wanted too and open that sound up a little bit! But be careful when installing and taking things out. Don't get any metal bits lost in the turbo or major damage could happen to it!
