I am looking to replace my OE catalytic converters with some high flow cats and will add a x-pipe after them for a little extra power...does anyone know a good brand of high flow cats to put on? I am goin to add the magnaflow x-pipe and want to know what cats would go good with that? any opinions would be nice

 

I would talk to some muffler shops. Im putting a 3" high flow cat soon, it seems like MagnaFlow or Eddlebrock are some good ones. I looked on Summit and some can get really expensive. I personally dont really know the difference between them, their all high flow so dont matter what you going to get improvement.

 

I was probably going to go magnaflow cats and the x-pipe to get that kind of horsepower improvement but thought maybe there might be a better cat out there...thanks
