How are these HFC's? I see alot of people have them but nothing comes up in the search function.

CEL Lights?

Gains?

trying to decide between these and ARK's Rspec Cats.... currently using Invidia Gemini Exhaust, ....looking for no drone or rasp.

thanks!

 

Haven't heard anything about those, but Fast intention HFCs and RHFCs have a good rep for not having rasp or drone.
