well for starters i agree with no problem.

get an exhaust, tranny upgrades and gauges, either digital tuner based, or mechanical

 

in your opinion what kind of exhaust and etc. should i go with

 

4" turbo back with or without muffler which ever you like more. I personally go with no muffler.

You can find MBRPs for pretty cheap

 

Your going to also need INTAKE, EXHAUST, & INJECTORS

 

what do you think of dynomax exhaust?

 

never used it so i cant give an honest opinion.

 

okay thats reasonable

 

Mbrp makes a real cool dual exhaust kit, you can do cat back or turbo back. If installed properly it looks awesome. I will try to post a picture of it later.

Unless you do a muffler delete these exhaust systems are not going to give you much more drone then you have now, a little but not a lot.

To the intake, I had afe stage 2, I don't think it did much for fuel mileage or performance, but it did make the Turbo whine a little louder. You will get differing opinions on air intake, the thought process is more air in and out is better. You have to identify if you are getting more in with an intake. But don't be confused on the lly it is not a cold air intake due to the location. (In my opinion)

 

The LLY also suffers from Induction over heating, i would look into getting an LBZ or Kodiak turbo intake mouthpiece, they are cheap and will help reduce restriction into the turbo, and replace your stock intake with one built for an LBZ it will help lower intake temps and reduce risk of over heating

 

I would also steer away from bully dog. There is better things out there and have the potential to be alot nastier than bully dog when you have the other mods to back it up. There is PPE or EFI live which are both on the lines of nasty as far as things go, but you have to have other mods to support the upper levels obviously.
