Do a little research and I think you'll find the 04.5 and up stock 4" exhaust is not all that restrictive. Unless you have to replace the exhaust because its rotting off, you can get a much bigger bang for the buck spending your money elsewhere. From what I've read, in order to have the "in cylinder egr" the turbo turbine has a small housing which causes quite the restriction. So spending big bucks on huge exhausts for extra performance without addressing that restriction at the turbo is kind of silly. Now if you want the sound or just need a huge pipe out the back to make up for other shortcummins.....
