This is a hr lower manifold and this is where I got the idea to make the de circle style more of a Squarish shape. Not quite as perfect of a square as this one but basically a slanted squareish circle with smooth edges. Why did nobody ever try this, and this seriously needs to be a thing has anyone tried this and got the results I’m getting. I can’t stop driving my car! It’s wayyy to powerful off this mod alone! Wtf
