So I would like to start off by saying I don't care about anyone's argument about duel exhaust, its my car and i do what i want to it, i don't care what you think or about your two cents. I do what I do and i don't mind helping like mined people do the same thing. So if your against duel exhaust just back out of this thread now, if your are into the idea and have been following my post here's some info.
The Nameless tips don't work (very well) with the stock 2.5 exhaust on my 2015. the gaskets are different and the flange bolts don't line up. Since I've got a fifth gen 3.6 mid pipe things are looking up. took off my stock mid pipe today and installed the 3.6 with zero issue. Flanges matched up perfect, hangers all match and the nameless axle backs work as intended with the 3.6 exhaust. the 3.6 mid pipe from the resonator back is a bigger pipe but no fitment issues. another good find i found was on the passenger side where there are not hangers welded in, it is easy to see where they go because there is metal that is formed for them (see picture) Until I get the hangers and weld them in I'm going to make a block off for the passenger side exhaust for now once i'm done with the block off I will give it to whomever for free if they would like to do the same set up as I.
