I recently bought pacesetter mid-tube headers i am installing them now. I also have magnaflow cat back. My question is if i replace the cat with a straight pipe would i need to do any tuning to my car? Or what would be my best option for replacing the cat?

 

just a curiosity

since you are removing the cat, why didn't you buy long tubes?

anyway, no, you don't need to tune but how many O2's on your car? You did not mention the year

 

I have a 94, there are only 2 02 sensors on my car.
