High Flow Catalytic Converters

[B-rad]

I'm considering having my OEM catalytic converters replaced when I have a new set of headers installed. Has anyone tried the High Flow Cats from Comptech? If so, is there any performance gain over stock or is it a waste of $750? My NSX is a '91 with 22,000 mi.

Performance gains from high-flow cats (or removing cats) are very minimal until you modify the car much more heavily, especially with forced induction.

hi-flow cats ae a waste of money IMO. You either keep the stock cats, or get a set of test pipes for much cheaper, and they will give you more hp.
