Sorry guys been away for a while.
Well Honkey_ Tonk I ran the tires last season and they worked very well. I used 35x12r15 for the show n shines and 235-75r15 for comp. I know you are thinking who uses such a small tire?? Well with the gears I run and the short tracks indoor you need the extra power!!
And to Full Size, More flow,more power. I run under closed conditions and people are a good ways back from the truck when I run. Besides It sounds really loud and chases off the competition.
We finished first six times out of seven last year so I think we are doing ok!!!
Those pipes look crazy enough to be a reason to do it. But in all actuality, Other than going maximum RPM at full speed, pipes like that will actually take away direct torque, there is a percentage of back pressure needed to make higher amounts of torque increasing acceleration from a stop or slower speeds. So for trucks/off road vehicles and such should always have some back pressure. In fact there is a race team down here I often get help from, They race only Mopars and that is the only reason why I know them. Even on there drag racers they putt slight cups at the tips to give a little bit of back pressure and have noticed better 1/4 mile time. But your method must intimidate the rest so go for it I have also confirmed this with a custom exhaust shop around here. A similar comparison (But Different) is why Dual Plane Intakes give more torque than single plane intakes and also would be recommended for a heavier vehicle.
