This is ZZP’s first exhaust part that we released for the Cadillac ATS and CTS 2.0 turbo.  This is the same part that is installed on Matt’s car which is the worlds fastest stock turbo ATS - we run what we sell. It is fully 304 stainless steel, so it will outlast the car and don’t forget the amazing TIG welding that ZZP is known for. Typical gains are from 10-20whp and quicker turbo spool. No tuning required, although it is recommended, and it bolts in place of the stock piece.  The stock downpipe is 13.5 lbs, while ZZP's catted pipe is 7.2 lbs.

We use a premium 400 cell cat which should not set off any check engine lights, however when changing any catalytic converter in new cars you run the risk of a P0420 code. 

We are currently offering $100 in store credit to purchase your stock catalytic converter back from you. If you're interested, take a photo of your stock downpipe and email it to We will provide prepaid shipping labels for domestic (U.S.) shipments. 

Revised 02/2020 with change of rear O2 placement to avoid any transmission line interference.  

Fits the following 2.0L LTG vehicles: AWD/RWD: ATS & CTS, & Camaro.
Does NOT fit Regal or Malibu, however we do offer the FWD version here: FWD LTG Downpipe/ O2 Housing

ZZp Down catted Down pipe

I can confirm it fits a 2016 Cts awd. Install was easy for doing it with jack stands. I did have to remove the Cross brace as it made it easier to install and remove the down pipe. total time took a little over an hour to install. Everything bolted right up. only issue I had was one of the nuts supplied to bolt the down pipe to the factory exhaust stripped out. No biggie though just used a grade 8 3/8 bolt which threaded into the down pipe ******. Once it was tight I just added a nut to the back side to keep it from backing out. No cel light or exhaust leaks it has been installed for 2 weeks now.

Wish I had installed this sooner

At this point I have quite a few mods on my 2019 Camaro and this is by far the biggest bang for buck. You can definitely feel the car pull harder. I haven’t had it retuned since install and I still feel like I’m closer to the 15-20 whp gain. Install wasn’t too bad, most of the time spent was removing the stock parts. It’s possible to install with just a jack but a lift is recommended. At first I thought I had a CEL but turns out it was just my intake coming loose during install and it went away in a couple days. In addition, the difference in sound is huge, sounds much more aggressive, even with the stock exhaust. Right now I have the zzp downpipes paired with a Borla exhaust and y pipes and the this thing is loud as **** for just a 4 turbo. Definitely recommend this upgrade and zzp in general

Camaro catted downpipe

I installed this on my 2019 Camaro and the quality was amazing, hardest part of the job for me was getting the bolts off the stock down pipe but after you get that out, this one drops right and doesn’t take much time at all, as for sound, I can’t really give a direct opinion about that because I also installed a after market exhaust at the same time, some People worry about the possible check engine light you may get but i ran this pipe for 4 month before I was tuned and never seen a light. Hopefully this is useful.
