ok well im debatin on puttin one of those high flow cats on my car.. i plan on gettin a cat back exhaust so i figure why not since im takin it all down anyway.. but heres the problem.. i live in PA. edmissions.. will they pass? seems like every other site i go to some say they will some say they wont..

 

Get a carsound high flow. No problems. My car just passed inspection here on the island not too long ago with one.

 

yea here in pa (well depends on what part) the emissions are super strict.

 

If you have a OBD2 car (96+), I don't know of any high flow OBD2 cats on the market.

For OBD1 cars, high flow cats like the carsound are legal.

 

from what ive read carsound cats go to **** real quick....unless i got my brands messed up, but search and learn

and even if the car is obd 2 a cat is a cat, u might have to make o2 wires longer or plug a hole or something tho
