So the True Flow XDI just arrived today and I am going to install it on saturday probably. My first thought when I opened the box was holy S**T this thing is F***ing Massive! Sorry for the asteriks, but it is necessary. lol This thing has a 5'' inlet, where the cold air actually enters, and the rest of the mandral tube is 3 1/2'' diameter measuring from inside wall to inside wall. This thing is going to pull some serious air in compared to stock!!! I am psyched to install it on saturday. It will make the FM 50 DOR sound even better. And yes I know pictures would be sweet, but I don't have a camera to take them with and to be able to transfer them to the computer so sorry.

 

Nice job, I love mine.
