I've been researching downpipes as that is my next planned mod. I'm leaning towards ZZP for quality, do I need the Angled 02 or will standard work? I won't be tuned for a little while, just want to make the exhaust sound better. Also, would an additional bung be a good idea in case of adding A/F Ratio on down the road. If so any good A/F kits? Not sure if Wideband is needed as I think you should also be able to view this metric from the OBDII port. Anyway, any input/suggestions? Thanks guys!

*ALSO! Any pictures of ZZP's downpipe would be awesome! Or any other downpipes you all like/recommend?

 

I have the ZZP Catless. Great pipe, and the standard o2 sensor worked for me. Noticeably quicker, too. The sound is phenomenal. Only thing is, it threw a CEL about 5 minutes down the road.

 

im looking into this as well so ill just wait for what others have to say

 

Well then the standard o2 sensor didn't work for you , the angled option spaces the O2 sensor far enough from the stream to not throw a CEL .

It's an awesome piece, was my first mod, if you're not going to be tuned immediately to avoid a CEL spend the money and get the angled option.

 

I have the angled o2 one, its never thrown a code.

 

The additional o2 bung is ALWAYS a good idea to have even if you don't plan on installing a wideband until a little later. It's much easier to just order it that way now rather then have to weld one in later down the line. In the mean time, just purchase an o2 bung cap and leave the cap on until the time comes to install the wideband.

 

Your going to throw a CEL without a angled o2. If your not going to get tuned for awhile just get the angled. BTW, check out BadMab, they have a really nice DP for $135 shipped with gaskets too. The only thing is you will need a angled defouler otherwise you will throw a CEL but they are cheap, around $15 IIRC.

 

Looks amazing! How's the sound? Hear the turbo better?

 

does it hav a bung on there as well for aftermarket O2?

 

I have ZZP catted and the sound is great! Increase in throttle response and the exhaust tone is amazing. You hear that performance roar even in DD

 

looks sick!

 

Any dp will do, with a standard o2 bung. The factory sensor is a wb sensor....

Defouler will help with not throwing a cel but cel will not cause loss of performance.

 

You do not need an extra bung because our standard o2 reads as a wideband...if you are not gonna get tuned right away then get the angled. I have the angled but am also tune. IMO $40 extra is not a big deal

 

Ok cool! Thanks!

Yeah I know it doesn't affect performance, I'm just a **** about CEL's

 

just ordered turbo xs catless dp

 

Sounds great, love it. Have since deleted muffler and replaced w/Dynomax bullet.

 

How do you like the muffler delete with Catless? On YouTube quality vids it's tough to tell, they seem to sound ricey/farty. I considered doing a Catless DP and then the HAHN rear section w/muffler delete but I'm not sure how I'd like the sound. I might start with the DP and then see

 

is it just me or did you remove the heat shielding from flange down to cutback connection?
