HFC Downpipe w/ Catless Secondaries

[Dugong]

Hi,

Kia Stinger owner from Australia here.

Does anyone have experience with HFC primary downpipes with the secondary cats removed? Most of the US options are 400 Cell whereas the only widespread Aussie option (XFORCE) is a 200 Cell HFC. Not keen on paying almost double the price but I am also concerned that the 200 Cell HFC won't create enough backpressure which (based off other threads here) will cause the turbo seal to leak?

I am looking to do a dynotune after installing replacing the stock primary downpipes rather than a piggyback - is it even worth replacing the stock primary DP?

Thanks,
