O/R Pipes and Emissions
What exactly do people with Off Road pipes do about emissions? Are these usually not DD cars? Or do you put cats back in every two years? What exactly are the benefits of O/R pipes anyway?

Most people just put the stock H back on when it comes time to smog. The benefit is a louder more aggressive sounding exhaust. Performance gains are up in the air. I actually lost low end power when I had an o/r prochamber.

Im glad im from Maryland, We do not have Emission testing unless you sell the car! So I can run any pipe I wan't cops don't nail you usually unless they can smell is from the car pouring out which in that case of being pulled over for speeding shut the car off! And be easy on the pedal here in MD and we are good to go! I was thinkings of doing an off road pro chamber not now Thanks GMAN im glad I found that out!

The loss of power wasn't too bad. I dynoed my car on the same dyno, but at different times with the stock catted H, o/r prochamber and prochamber w/hi-flows. Weather was not really an issue, the dyno is already SAE corrected. Here are the numbers:
Stock catted H-297RWHP/309RWTQ
O/R Prochamber 302/RWHP/305RWTQ
Prochamber w/hi-flows 305RWHP/312RWTQ
As far as sound, prochamber/hi-flows sound the best.
