Catalyic Converter

[joefarrugia]

I removed the Catalyic Converter and cannot figure out the amount of bhp i added to my car, i also changed the silencer to a sports version. Can anyone let me know how much bhp did i roughly add?

Thanks

Probably around 2.5, but you're also !Removed! your computer. If you just sorta left the O2 sensor out, it's not reading the air correctly, and will start throwing a CEL, and you'll need to reset the Battery and get a little black box hooked up in place of the sensor. the Cat is highly restrictive, but unless you get rid of the muffler, you can't be adding much more than 2 or 3
