What are the Positives and Negatives of removing Catalytic Converters?
1)Apart from Not passing emission tests, polluting the environment and the illegal nature of not having cats.. are there any other negatives?
2) Are there any back pressure issues?
3) Any loss OR improvement in low end, mid range or top end power?
4) Is it true that fuel economy improves when the cats are removed?
5) Is the NSX considerably louder with the cats removed (on and aftermarket exhaust system)? 10 20 50 100% louder???
Cheers
