Hey besides passing emissions testing, anything wrong with using an O/R H pipe?

You'll need a pair of MIL eliminators or have a tune to turn off the rear o2 sensors.

Not that i don't like the environment or anything but Cats are expensive (for me atleast

) , was looking into high flows... Would having O/R do anything performance wise? Losing/gaining hp or anyhting

I know our cars are different but I was reading a tuner magazine where they gained 3hp from stock to an test pipe aka o/r pipe. So not much but like I said this was on a 4 banger idk about our cars.
