me thinks 4" will be a bit much flow unless you are running a 5- 600 hp diesel. dual 2.5 should have alot of flow w/o torque sacrafice for 400hp gas

I feel that tq loss is a misconception when doing a 4". It would be hardly noticeable if at all. If you can get past the rasp the 4" would be easiest and more than likely make at least the same power as a dual setup. If you're going for unique then do the dual setup. It's been done but not by many.

Perfrmance Headders ---> True dual 3" all the way back.
No H pipe, H Pipe, cats or Muffers. Just raw engine.

My, my, I wonder what this stuff is for?

That's what I'm talkin bout! This is very, very similar to what I want to do on mine. Did you build the tail sections, or is that manufactured pieces?

I cheated a tiny bit with that, it is a stock raptor tailpipe setup. Now to wait for my off road downpipe...

That dual 2.5 will flow nearly triple the single 4 will

Be sure to post pics and vids through out. If you have a stock system on it now id ask if you could do me a huge favor by taking the stock resonator out and revving it some with the stock muffler on it so I could hear it. I just got my 2013 in a week ago and don't like how any systems sound so far. I'm curious on the sound without the resonator and stock muffler. I'd like a little deeper sound but not a lot louder than now.

WAY BAD

Rite on man! Nothing wrong with that. I think it's going to look trick! I'm hoping it's going to sound as good as it looks.

I will do the pics and vids for sure, but I have no pipe that will bolt onto the stock "res" location for that. There are a few vids on here of the off road pipe with deleted res. Funny thing as well, what everyone calls the resonator is actually the muffler and what people call the muffler is actually the resonator. Fun fact for the day.
