has anyone replaced the 4 stock cats and replaced them with 2 high flows. if so who made them

 

I have two high flow Magnaflow cats on my '97 F-150. Took out the four stock ones and replaced them. Went with true duals all the way back to a 45 degree bend out from behind the back tires. I didn't straight pipe it though I put race mufflers my older brother had on it, there only like 12 inches long (give or take).

 

What cats did you go with?

 

which magnaflows did you go with and are you experiencing any engine light issues.
