rk sport's o2 simulator brags 15 horsepower and 25 ft/lb power increase. is this true or even close to possible? i understand that it's needed for installed an aftermarket catalytic converter, but by itself, will it do anything near what it claims? please leave comments and suggestions about this or similar products. thanx.





I'm making the back of my car look good first.
After all, Civics need something nice to look at...

LOL!! i never heard of it increasing hp. and if done right, you wont need an 02 sim for an aftermarket cat



Im a Xbox 360 fanboy...and damn proud of it!!

do not buy it it wont work on your car
