I agree it is an easy install, took me a couple hours to do. But later had to do a little re-adjusting. I installed MBRP's "Cool Duals" turbo back on my '04 and with the cat installed it sounds nearly stock. Since they don't check for cats on diesels where I live I later installed the cat delete pipe and I definitely like the way it sounds now. Sounds much better under exceleration, and more turbo whistle, too. I like the fact that while cruising along it sounds stock, but downshift and get on it and it sounds sweet. Haven't tried without the muffler, tho. I noticed a quicker spool up on the turbo but it still has some lag. My system is 3.5" from the turbo back to just behind the cat, the delete pipe is 3.5" also. From there back it is 4". Later plan to install a Banks Techno-cooler. We'll see how that helps the turbo lag.
