catless downpipe concerns

2262 Views 13 Replies 7 Participants Last post by  Johno1412
I am planning on modifying my exhaust; my plan is to buy the zzp catless downpipe and bolt in an exhaust cutout on the stock midpipe. If the primary catalytic converter is removed will the secondary catalytic converter be able to handle the extra chemicals or will it clog soon? If clogging turns out to be a common problem I will get the zzp midpipe that has the catalytic converter. Thanks for the help :)

I have the ZZP catless downpipe and their mid pipe with a cat in case of inspections. Zero problems and have had them on for about 30,000 miles. Keep in mind I am tuned so I don’t have to use any O2 extensions

Can you take a picture of what you are calling the second cat? I only have one on my 2014 Cruze.

You definitely have two if stock exhaust. It’s further back on the midpipe.
I have (had) a resonator there, not a second cat. I still have it in a box somewhere.
