Aerie Y Pipe

[crashprash]

Technically, if the Aerie Y-Pipe is a larger diameter than stock, it will get louder. But if its the same size, then no benefit unless the bends are smoother than the stock one.

the bends are smoother than stock for one of the exits of the "Y"

I want to create an exhaust with the letter of the alphabet prior though ;-)
