Can I have a down pipe with cats?

Does adding a down pipe mean you have to run without catylitic converters or are they in between the downpipe and exhaust/catback in my case.
Thanks

The downpipe and cat are 2 separate parts. Look under your car for more info. We are not a Subie...we have one cat.

You can but putting a downpipe on there and no high-flow cat or test pipe kinda robs the amount of air that flows through. Open her up and give her a highflow cat or test pipe

some down pipes will come with the cat delete as part of the pipe too (one solid pipe). I personally would run one with the sections seperated so you can put the stock cat back on when you need to.
