Where could I find a good flowing single 4" in dual 3" out y pipe? somthing decently compact would be great.

custom...you can use the FLOWMASTER merge..Its waiting in my garage when I'll be going with the 1 7/8 TSP headers next year.

That would work but i dont see that in a 4" inlet 3" outlets. This is going to be used to split my 4" downpipe off the turbo into dual 3" to go over the rear axle.

I may be looking at the sizes wrong.

You should be able to use a Vibrant 2-1 merger #10362, since they look like they should flow good in either direction. It'll run you from $95-$130

BTW, it's(#10362) only 10" in length.

Here's the one I put on my exhaust:

you can still use flowmaster in reverse. but its not very compact, its huge actually. custom might work too.

I REALLY love the look of that piece.. but 2.5" inlets? And those seem so damn close, how are you going to get the clams around there? Weld it?

Thanks just what i was looking for, sure looks good too.

Yeah I have the 2.5" inlet/3.5" out merger replacing my BBK Y-merger. The 2.5" pipes aren't the restriction on my setup, the 3" exit was.
The dual inlets are slip fit, then once everything is where you want it you'll need to weld them up.
FYI, the merger I listed for Chevyboy82188 #10362, has 3" inlets and a 4" outlet.
