[Shotimes] custom y-pipe?

If he's doing it for performance, he would probably gain a flow improvement with a 2 1/2" outlet since this would eliminating the restrictive merge into the single 2 1/4" pipe. Though, he would also have to replace the 2 1/4" resonator pipe with a 2 1/2" to gain the flow improvement.
