LSJ downpipe needed
Anybody in the Phoenix area have a stock downpipe for a 05-07 SS/SC they can spare? I managed to come in to a friend's garage a little too hot & caught my resonator on the steel angle-iron edge the floor had...


I fortunately had a catless ZZP mid-length header combo sitting on the shelf waiting to be installed, so I've been able to get by, but now emissions are due & I'm throwing CEL for O2 values too close... It wouldn't be a big deal, but I'm deploying soon & running out of time to get this taken care of.

Can anybody help me out?

get a zzp higflow dp. not the 3 inch, a 2.5 inch hiflow with stock header its not lsj specific. it wont set a code at least in a year on my lsj it hasnt set it.
another way is geet a angled o2 sensor, takes 2 seconds to install and works usually

I've got a zzp catless on the car right now, but emissions are due so i need a catted one so that I can register it.

im aware of that, i said to get a highflow 2.5 catted downpipe from zzp, ive had one for a year and have never had a p0420 catalyst efficiency code pop up. its like 160 bux i think

or buy a angled o2 bung to get rid of the code, and hope that they dont look for a cat during your inspection.

I appreciate the suggestions bro, but I don't have the time to wait for it to be shipped here. I just got back from Afghanistan & am trying to get my life back in order.

I had hoped that someone local might have an old pipe lying around so I could push the easy button on this & start getting my stuff out of storage to re-establish normalcy.

I'll just have to get a shop to add a high flow cat to my existing pipe if I can't find one before I run out of temp tags.

go to a junkyard and get one off a basemodel, or find one on craigslist from a base model. its the same as a stock lsj dp. thats probably your best bet. they may weld it on your catless dp and u still have a code after.. but whatever u decide hopefully it works out
