i'd probably drop it back to a 2.5" exhaust since you won't outflow it on a 7afte.
and if you can, find a compressor map for that turbo, i'm not familiar with a CT9? but find out what turbo you exactly have and i can do some math on the compressor map to see what u should be getting up into that range with that turbo..
