titanium won't weld to aluminium.

The weight you cut by going with titanium is so small in the grand scheme, its not worth it. Al isn't that massive, and is cheaper than Ti...You won't offset adding a heavier IC by using Ti for your piping.

this will fill the gap of an S4 bumper

but the top/bottom design is "optimum"

and no more than 2.5" for a K04. You don't want to get too crazy with the size. Stick with 2" piping.

I've got a 3" that will be going behind an S4 bumper. Initial measuring says it will fit, but I haven't actually tried to put it in yet. I'll get in there somehow

a 3" will fit behind an S4 bumper, but you'll most likely have to trim some of bottom of the bumper support, depending on the height of the core and it's placement.

I don't think I'll need to cut into the bumper support, the core is only about 6" high.
