Pride high flow cats or resonated test pipes?

[stallion777]

Hello guys. I have a NA2 3.2. Engine is stock except for a pride v2 quad exhaust, a UNI filter, and a downforce side scoop. I still have stock cats. Thinking of getting a order from Pride. Either high flow cats or the resonated test pipes. What advantages and disadvantaged should I expect from either compared to my stock cats.

You'll get a CEL on OBD2 without cats. Not sure if you will still get it with the HFC but you could probably fix that with an O2 spacer (correct me if I'm wrong about this on the NSX). I have been running the pride HFC for almost a year, no complaints. Test pipes have more flow, but unless you're planning a huge HP setup that probably isn't a big concern...

Thank you. I went and bought the high flow cats. Installed and they sound great. No complaints or lights at all.
