i have cats, and mine still sounds awesome. mine has quite a bit of rasp, and when it first starts in the morning, im pretty sure the whole neighborhood wakes up. if i dont remote start i try to sneak it in gear so people can sleep in! my truck sounds way better once its warm. not sure what causes that, but the sound has also gotten better with a few thousand miles.

You're just going deff in your old age, lol...

The high flow cats from SW are what they say. I had cats took them out don't think there is any difference. You can see streight threw the SW cats. I don't regret taking them out wasn't sapose to be on in the first place.

I do agree that the cats are very efficient. However, no cats will always produce more power than with cats. Whether you notice this by taking them out and driving on the street idk.

I couldn't tell any difference in mpg or power. I'm happy they are gone I believe what your saying is why I got rid of mine.

no cats make more power and wake the dead....
