Motordyne TDX-II + HFC?
Hey guys and ladies,
I've been doing a lot of searching and not getting a lot of answers... Looking to add HFCs to my Motordyne TDX-II catback. I would LOVE to do test pipes, however I autocross in STU which requires cats within 6" of the stock location.
The goal of this modification is to free up what seems to be the most restrictive part of our exhaust, while staying STU/street legal, and not sacrificing sound. Initially I was looking at Berk HFC and Kinetix (even Z1Motorsport), however have found many people stating they are loud and there is a hiss to them.
My latest research has pushed me towards resonated HFCs. And that brings me to two options:
ARK resonated HFC
Fast Intentions resonated HFC
In your opinions, is resonated the way to go (worth the money)? Who has some experience with these products? Any videos? How about mating them to my TDX-II?
Thank you in advance for your help, and if there are any threads that I've possibly missed in my browsing please point me towards them!

Thanks for the input! Are you currently running Berk? Any thoughts on Z1 HFCs?

About 2/3s down it explains cell count vs flow, seems flow is directly correlated to cell count and length.
I'll start checking around for flow rates through the aftermarket cats though, good thinking!
