looks pretty straight forward. As long as you have the tools and a way to get under the car with enough space, safely, I think it shouldnt be too hard. Here is the instructions from Roush's page

Does anybody know if the Roush O/R Exhaust is "drive-by noise legal" in California?

 

Is that Roush kit just straight pipes no muffler? It says "Off Road", what does that mean? Wouldn't straight pipes be too loud to be legal? I'm not sure I want it screaming loud.

 

It has resonators closer to the front instead of mufflers after the axle. It says off road for legal reasons. It will be louder, but its not like straight pipes. You still have your cats installed, and the emissions stuff remains the same so you should be fine with passing a smog test.

 

Cool, thanks man.

 

Any drone while driving at speed? I know it needs to sound nice but sometimes the drone kills me.

 

I drove to Atlanta today and noticed slight drone at 70 MPH but moving speed a few MPH below or above that and it goes away....
