inlet pipes. Its a matter of getting between the manifolds and the motor mounts. There are others who have sucessfully fabcricated some inlet pipes with some effort.
ps. I bought the ams manis/ alloy toyz dps used. I would have bought the MSP manis and SZ 3" expansion dps if it was selling for $700 and $450 new respectfully like it is priced now. $1100 for manis and $750 3'dp's was a bit much. For what its worth, you win this battle but I've resold some MSP manifolds and SZ 3" expansion whenever I come across new Z fanatics.
