Just had a discussion with my M3 friend about cats. He has high flow cats on his car and claims there is a measurable difference.
Why doesn't anybody sell a high flow cat for the NSX? Because removing the cats doesn't increase horsepower in the NSX? If this is the case, why does it make no difference in the NSX when it does in so many other cars? Does the NSX already come stock with high flow cats? What is different about the NSX engine that yields no gains?
