I could only find plastic at the time. Just add a 45 to the existing pipe you have and you'll be good.

Get a plastic 45-degree piece made by spectre and get that filter farther out and towards the fender. IATs will be better than the stock box. I've tried about every setup, and this ended up the best. I'll take a pic after work.
I used a dragy unit and picked up over .1 0-60, the 1/8 and 1/4 mile which is equivalent to 10hp. Plenty of info on ecoboost motors picking up 10 hp/tq. I gained 1-1.5 mpg based off off of an average of about 400 miles from tank to tank.
There is a DP available. PM Ivang79. I'm going to get one soon and gut the 2nd cat. I'll keep the stock muffler. It should sound and perform great. These things move out with just a tune and intake. I'm running an open style homemade 4" intake. I ran with a box for a while. Same 1/4 mile times...
5 star E30 tune and a homemade intake and this truck will run 13.60s. Fx4/4k tow no weight reduction with 3/4 tank of fuel. This was with the base tune and only 20 miles on it (the tune, not the truck). It will only get faster!
