Catted vs. Cattless DP
Couldn't find the answer I was looking for via search, so...
Now i understand, unless I don't that a Cattless will yield better results. Now I want to remain emissions happy, so will say a HAHN catted DP make me happy or any other known brand or is it catted or gtfo?

you will not pass emissions if you go catless dp without a tune. You are going to have to get a tune to disable the code but with a tune you will pass emissions only if they dont look under the car. I have worked at a shop and have never seen anyone look under the car for a cat. and you will net better gains with catless over a dp with a cat.

The ZZP catted does look appealing, plus it's cheaper . Btw I got a n00b question on having this baby installed. Does it bolt right up to the rest of the exhaust? Also what would be a fair price for an exhaust shop to install as I dont want to do it myself?

It's 7 bolts and and O2 sensor. There's a how-to guide on it as well. Do it yourself. It takes about 1/2 hr.

If they do an emissions check, you will not pass no matter what. The cat filters out exhaust gasses that they test for in emissions checks. Catted will never throw a CEL, but cat less may or may not, it's hit or miss. Cat less has better gains, but a catted dp will still show good gains over stock. Cat less is louder.
I plan on going catted because I'm not gonna get a tune anytime soon and I don't want to deal with CELs.

ZZP dp ftw, damn good price better then the rest of them out there
The catless dp with stock exhaust isnt loud at all, not even at start up, some people just have virgin ears
Why would you want to have it quiet, if thats the case you mise well leave the exhaust stock and just get the gms1

ZZP Catless here.
And the car is still quiet. It only get "loud" when the wastegate opens up. And even then it isn't that bad.
During it's warm up phase is the only time it is loud. If you wanna even say that.
