[katdude123]

hi every one, my question to u is that can i put "true duels" on my truck the brand i chose is flo pro by the way so is there a way this can be done because i want power and economy and also can i remove my catalytic converters and get new pipe put in is it possible to do this?? well i think so because right at the collecor right after the cats i was think ing if you put new pipe right from the manifolds all the way to the back and cut out all that and instead just get pipe put there sde x sde would it work or not??

Yup completely possible. Its done quite frequently actually. The only thing is have a qualified professional ensure that the proper pressures are the same for both sides. IF you have more back pressure on one set of pistons than the other it could lead to valve problems or the motor just wont run properly. Knock Retard is an intake an exhaust operation and if either component is malfunctioning the computer will try to change the mixture automatically to either a lean or rich condition. I know some folks may advocate an O2 Sensor delete but those sensors are actually a critical component not only for emissions purposes but for the computer to ensure proper fuel/air mixture. It doesn't necessarily matter the brand of exhaust you use just the diameter of the pipes and symmetrical mufflers. Make sure you also determine whether you want to maintain low end power or not. When going on a bigger diameter pipe than stock you lose some exhaust back pressure and consequently low end torque.
