I was thinking about removing the catalitcic converters from my gt mustang it's a 2005 what are the pro/cons to this besides the state emmissions requirements.hp gain how much nose diffrence

Can't do it! Fed Law. Plus, there's an 02 sensor to read after the cat results to put the car's computer in closed loop. You'll have check engine lights galor!
There's no pro to this. Just con's. Seriously, leave them where they're at. Go for the cat-back systems.
