i have 98 v6 mustang with a cold air intake with staight pipes coming(not conversters) from the headers. every since then it feels like my car is soimewhat choking when i accelerate somebody help , could it be thaty i am runniing rich on fuel or maybe it is more air going out then coming in

 

You definitly need a cat or something to provide some back pressure. You probably don't any low end torque at all. Also did you install mil eliminators? You need to or your car is going to start running really rich.

 

Zach is right on. You need more back pressure on a stock engine and a mil elim if you remove your cats. You can go catless, but you need mufflers, smaller dia. piping and a mil elim.
.....or a totally built engine. [sm=smiley20.gif]

 

you need more pressure for your intake engine so you can get better performance
