Default DC Sports HHC5012 header

My son has a catless catback exhaust. No header. Stock manifold upfront. Any issues I will face with installing this?

If you have a cat back exhaust it is from the cat back.
there for if you have a cat and your exhaust is made for the car it is just a bolt up deal. simple install.
If the cat is not factory and mount holes are not factory it will need some sort of welding.
A cut off wheel can help in removal
you may need a test pipe or racing cat if it is missing
if i have read this wrong.
title is for a DC header with a cat less cat back exhaust?? But you only mentioned catless exhaust, and factory header in the post. 🤔
With a cat back exhaust i have a 2.5 inch cat back and is a direct fit to the cat.
I am not sure but if your dc header is larger say 3” because you turboed it. It most likely will not work.
or maybe your catless system is just missing the cat and has made up for the cat with length.
Or just try to install it. See what happens.
or do not listen to me. maybe others will have a better opinion or have done what you are randomly asking??

Sorry if it was confusing. He has a test pipe, to a cat back exhaust attached to the stock intake manifold.

Won't have any fitment issues but if you haven't bought it yet, I found the DC overpriced depending on your needs. Talking from experience, if your exhaust is upsized at all the DC will provide flow restriction with its very small collector diameter (1.75" I think).

Better off looking for a header with a larger collector or one at least the same diameter as the catback
