Noone runs anything this big in the gas section so I thought I'd ask here.
I'm looking for a 4" to a dual 3" outlet collector to run after my turbo.
I will run 3" from the collector back for better flow than I currently have.
Also adding a 4" I.D. resonator to cut the sound just to make it a little more acceptable to cops....and my wife.
Anyone make such an animal??
Thanks guys.

 

I am sure an exhaust shop could fab it up for you... I am not sure where you could get one off the shelf though.
