So my current build is as follows:

AMS Downpipe
ETS Catback
Resonated Test Pipe
AMS Intercooler
AMS UICP
AEM Intake

I forget how much torque I am currently running but about 356 HP. Also, the stock manifold has a hairline crack in it so I have decided I will replace it. I have also decided to move to a High-Flow Cat to get rid of the strong exhaust smell that occasionally enters the cabin as well as tone the car down a little bit for long road trips.

My question is, what other mods should I pursue at the same time? Since I will have to re-tune the car, and the turbo will be off anyways, I am wondering if replacing or having the turbo upgraded through MAP will provide worthwhile gains.

The plan is as follows:
MAP Tubular Manifold
ETS High-Flow Cat
MAP EF2 Turbocharger Upgrade Service....? (I'm open to other recommendations)

I want to be making the same, if not slightly higher power after the mods, but keep in mind this is also my DD, and I want to tune the car for longevity not necessarily for max performance. Thanks in advance.
