OFF ROAD!!! It will sound AWSOME with the Stingers

 

OK one more ? if i have cats on the exahaust system y do i need them in the X pipe?

 

they are a special pos that has to do with emissions. usually if you dont have em, the sensors will go off, and you couldnt get it inspected. all cars are supposed to have all parts on them, that compare to stock form. you can upgrade as much as you want, just they are supposed to meet stock specs. right now you should have some sort of crossover pipe with cats. so, the new pipe is supposed to have at least one on each side, but if you get the mil elim. you can pay alot less, and make it sound better.

tim, what about the o2 sensors?

 

high flow (catted) is like 200 bucks more expensive, but will pass emitions. offroad will be louder, but due to newer technology, highflow generally give almost as much HP as an offroad pipe.
