Question Installing my first catted Y tommorrow.

I can't afford headers right now but cant stand looking at that flattened out joke of a pipe on my car, so I'm throwing on a 3 inch y pipe I have. I first posted this in the wrong section so it's been moved to the appropriate section, here. So I'm doing this install either way but I'm just wondering if:

A) this will help performance/flow and by how much?

B) Will I still run into banging y pipe issues even without lts?

*it's gotta flow better than the flattened out pipe that's on it right? How it's worth it to have a squished up pipe to gain an extra half inch of clearance is beyond me .

If its going to be custom then it shouldnt bang at all.

Yes it will help flow, how much, it depends on the merge going to be used.

According to the Mod Guide sticky it's not worth it:
- Do Not invest in a new Y pipe unless you plan to stick with shorties/stock manifolds, and even at that it’s barely worth it since you'll gain practically nothing by a new Y on stock manifolds. If you buy a new Y for stock manifolds/shorties you'll need to replace the Y you just bought if you add LT's or mids in the future.
Btw, great sticky if you haven't seen it already:
