Potential y pipe issue

[1882]

I have the y pipe awaiting install but have a few concerns. Magnaflow's site says it's intended use is single in dual out. Of course we all know folks that are installing them are going dual in single out. My concern is if you look into the y pipe looking in from one of the 2.5 inch "inlet" sections looking out the 3 inch single outlet you will see potential for significant turbulence. The reason is the round pipe section of 3 inch outlet protrudes into the y section around a half inch or so leaving a "collar" of sorts that is far from smooth in flow potential. Has anyone else noticed this? It actually looks like it just might flow better than single in dual out as the same problem exists but you then have two "collars" to add turbulence. Am I crazy or is this concern valid? Many thanks!

maybe you could file it down with a rat tail file or a dremel tool with a long deburring tool? Smooth the flow ya know.

This looks to be the only option but would indeed be labor intensive and time consuming. I might take it to a machine shop.

Have you seen the factory setup??? Now THAT is awful....

The Y is TONS better than that for sure......

The factory y is crushed but most likely has no internal collars like the Magnaflow while the Magnaflow has greater volume yet retains the turbulence. Not sure which is the lesser of two evils, I'd love to see some flow bench data.
