If the msds headers and stock manifolds are 2", I wonder why their y-pipe is 2.25".



2.25 is alittle too much flow for a down pipe. Since u are losing the 180 bend you lose tha tmidrange power, and then an increase in tubing you would really suffer down low and mid. You would probably mainly feel power above 5k. 2 inch is perfect. Many on here that get dual exhaust go 2" from headers back. MHO get you stock optomized!!!

I reject your reality and substitute my own.
