Some questions like these we will probably not know until people install them and run the tests. I barely passed california smog with 400 cell cats. I'm planning to get the 300 cell and seeing how it goes.

I have a question for people who have run 100 cell cats in the past. Does the car still have the straight pipe exhaust smell with the 100 cell cats or not??
