DP...Hahn VS. CIA VS. ZZP
It took me and a buddy and a lift... about 20 minutes (if I wouldn't have stripped the stud) luckily my buddies shop had one there so we just put it back in.
And yes there is a "BIG" change!

Depends on the code... if you throw an o2 code it could cause... lean or rich conditions making your car run... but not well.
Do yourself a favor get the angled bung... or get a cat (if you aren't tuned)....

i am going to get tuned, i have the hahn cold air intake, muffler delete, dejon bpv spring upgrade, and just ordered the adm downpipe, but dont want to get tuned until i get my charge piping! to get the most out of my mods, unless someone on here knows how to tune me for charge piping id just have to be easy until i get it
i just wanted to get the ic piping first because my factory piping popped off already (i fixed it ) but i have noticed that at higher rpms the stock hot side of the piping has alot of flex, i really want to do it right looking for 325whp maybe a little more is it dooable on factory piping

DO NOT STRETCH THE O2 SENSOR/WIRING - if you did - you could and will strip the wiring from the sensor, that's because the motor will move back and forth, its happen to a few guys already, that's why most guys returned the CIA & ZZP DP's.. that plus CEL kept coming on even if CEL got tuned out..
if you cut the O2 wire - get ready to buy another one.. that wire is super sensitive if cut..

WOW dude, you need to relax. It's not STRETCHED it's mainly MOVED!

ok man.
so ur going to try and save money.
I would advise on the catless DP from CIA. its bent when you order it. the welds are amazing. and everything lines up.
Running staight pipes on catless sounds like garbage. really ricey.
Dont use the dejon BPV spring. this has been discussed many times.
took me half hour with jack stands to take out the DP and put the CIA one on.
The o2 sensor lines right up. no Codes. no problems whats so ever.
and as far as IC piping go. it is honestly a great way to go.
Im doing CIA piping as well. the performance not the dress up. 30% less piping and a lot better airlflow...
when you get tuned. tell ur tuner that ur getting or have CP. they have to raise ur rev limiter for the CP.

Have you actually ever HEARD a catless D/P on a stock catback car.... It sounds ******* good as hell... NO RASPY, just a deep grumble on THROTTLE!
CIA... was my first choice but they told me they wouldn't split up the hot and cold side pipes so I went with a company that would!
If I decide I don't like these... I will swap them out and get the CIA pipes!
Don't be a brand nutswinger, I buy parts for a reason... not hap hazard!
I also have the Dejon spring... once again NO ISSUES after 3000 miles!
Yeah, i have the Hahn CAI, CIA IC Piping and i just ordered my ZZP DP. CIA turned me off simply bc iv been waiting for over 2 months since the GB has ended for my IC Piping

I took my dejon spring out because I was seeing some flutter when letting off the throttle, and few have had issues with burnt out BPV solenoids.
I thought better safe than sorry in this case. I think the stock exhaust with a Catless DP sounds pretty good but I like the way mine is now a lot better. When I first got my Catback It was kinda raspy and popped back some but it sounds better now as the muffler has broken in. 
WOOT
