Im currently using the zzp catted dp. Mine is the older 200cell cat with the angled o2 bung. Im running the gm factory performance tune and so far it has set no cel or had any running issues. Im happy with it, it made the factory exhaust a bit louder and pops from time to time. If your gonna get tuned anyway id go with no cat dp, if your in a state that has to have a cat they have the new 400cell that is still a lot more flow than stock but is legal and is even better at not setting a cel

I would just get the dip from ZZP and make sure it has the angled bung. Up to you in whether you get catted or catless. Catted on a stock turbo only loses like 4-5hp over a catless if it matters.

go catted!

I have an 09 with 3 inch zzp catless turbo back and it STINKS, I also have an 08 3inch turbo back CATTED and its so much better to drive (especially with the sunroof open). Go 400 cel catted 3inch zzp man i promise you will thank me later. screw catless unless it s a track car. (some will disagree with me) but i absolutely CANNOT tell a difference in pull.
